   Free Salesforce platform for building and publicly sharing interactive Tableau charts, dashboards and maps, with a free desktop edition.

   Best forstudents, job seekers and creators working with public data

   Adoption data

   over a million creatorsTableau says the visualizations on Tableau Public were made by over a million creators around the world.

   Tableau (Salesforce), About Tableau Public (2026): “With millions of interactive data visualizations made by over a million creators around the world”

   Tableau Public gives away much of the Tableau chart builder for free. You can author in the browser with nothing to install, or download Tableau Desktop Public Edition to work offline and save files locally. Data comes in from Excel, CSV and Google Sheets, and charts, dashboards and maps are built by dragging fields onto a canvas without code. Tableau hosts the finished vizzes at no cost and says they can handle millions of viewers, which makes it a good place to publish a portfolio. The community is large: Tableau says over a million creators have made the millions of vizzes on the platform, and any public viz can be opened to see how it was built. The trade-off is clear in Tableau's own terms: it is a platform for public, not private, data, so anything you publish is visible to everyone, and data refresh is limited. For private dashboards you need a paid Tableau plan or another tool on this list. We compared documented features and published terms; we did not run hands-on tests.

   Strengths

   • +Web editor and desktop app are both free
   • +Hosting is managed by Tableau at no cost
   • +You can see how any public viz was built and make your own version

   Limitations

   • −Everything published to Tableau Public is visible to anyone
   • −Tableau states data refresh is limited
   • −Private sharing needs a paid Tableau plan such as Tableau Standard

   SummaryTableau Public is the best choice for people with public data who want a full chart and map builder for free, because both the web editor and the desktop edition cost nothing. Pick another tool if your data must stay private.

2. 2

   Microsoft Power BI Desktop

   Microsoft's free report authoring app for Power BI, with data modeling, DAX formulas and hundreds of data connectors.

   8.8overall

   Microsoft's free report authoring app for Power BI, with data modeling, DAX formulas and hundreds of data connectors.

   Best foranalysts already working in Excel and Microsoft 365

   Adoption data

   30 million monthly active usersMicrosoft said in December 2025 that 30 million monthly active users rely on Power BI.

   Microsoft, Power BI 2025 holiday recap: a decade of innovation and impact (2025): “30 million monthly active users now rely on Power BI for insights”

   Power BI Desktop is the authoring half of Microsoft Power BI, and Microsoft offers it as a free download. It is a serious analysis tool: Power Query handles data prep in a way Excel users will recognize, DAX gives full control over measures and models, and built-in quick measures, grouping, forecasting and clustering go beyond what most free chart makers offer. Reports draw on hundreds of visuals from Microsoft and partners, and you can build your own through the open source custom visuals framework. Connectors cover hundreds of sources, from Excel and SharePoint to Salesforce and Azure SQL Database. Microsoft reports 30 million monthly active users of Power BI. The catch is sharing. Microsoft's pricing page tells you to upgrade to Pro or Premium to share reports, and Power BI Pro is $14.00 per user per month, paid yearly. So Desktop is free for building and for personal analysis, but a team that wants to publish dashboards will pay. We compared documented features and published prices; we did not run hands-on tests.

   Strengths

   • +Full report authoring at no cost
   • +Forecasting, clustering and grouping are built in
   • +Large user base, with 30 million monthly active users reported by Microsoft

   Limitations

   • −Microsoft's pricing page says to upgrade to Pro or Premium to share reports
   • −Power BI Pro costs $14.00 per user per month, paid yearly
   • −Steeper learning curve than chart makers such as Datawrapper because of DAX and data modeling

   SummaryPower BI Desktop is the best choice for Excel users who want deep, free report building, because DAX, Power Query and forecasting are included at no cost. Budget $14.00 per user per month for Power BI Pro once reports need to be shared.

3. 3

   Google Data Studio

   Google's free reporting and dashboard tool, formerly called Looker Studio, with connectors to more than 1,400 data sources.

   8.7overall

   Google's free reporting and dashboard tool, formerly called Looker Studio, with connectors to more than 1,400 data sources.

   Best formarketers and small businesses who need private, shareable dashboards

   Google Data Studio, which Google renamed from Looker Studio, is the free tool on this list that best handles private dashboards. Google's pricing section says it is available at no charge for creators and report viewers, and the self-service tier remains free. Reports are built in a drag-and-drop editor with filters, images, text and multiple pages, on either a pixel-perfect or snap-to-grid canvas. The connector list is its main strength: Google says you can connect directly to more than 1,400 data sources, including Google Sheets, Google Ads, BigQuery and Google Analytics, with over 1,300 Community Connectors for other databases and apps. Reports can be shared with people and groups, edited together in real time, or embedded on a website. Data Studio Pro adds team content management, admin features and Google Cloud support for $9 per user per project per month. Google publishes no user count for the product, so we scored adoption conservatively. We compared documented features and published prices; we did not run hands-on tests.

   Strengths

   • +Google states it is available at no charge for creators and report viewers
   • +Reports can be shared privately with individuals and groups
   • +Native links to Google Ads, Google Analytics and BigQuery

   Limitations

   • −Team content management and support need Data Studio Pro at $9 per user per project per month
   • −No published usage figure, so adoption is scored conservatively
   • −Fewer modeling tools than Power BI Desktop

   SummaryGoogle Data Studio is the best choice for marketers who need private dashboards for free, because creating and viewing reports costs nothing and it connects to more than 1,400 data sources. Teams that need admin controls can move to Pro at $9 per user per project per month.

4. 4

   Google Sheets

   Google's browser spreadsheet with built-in charts and pivot tables, free with any Google account.

   8.6overall

   Google's browser spreadsheet with built-in charts and pivot tables, free with any Google account.

   Best foranyone who needs a quick chart from data already in a spreadsheet

   Adoption data

   10 million businessesGoogle said in 2025 that Google Workspace, the product family that includes Sheets, has served more than 10 million businesses.

   Google, Google Workspace enables the future of AI-powered work for every business (2025): “We've empowered more than 10 million businesses of all sizes”

   Google Sheets is not a dedicated visualization tool, but for many people it is the fastest free way to get a chart. Google says anyone with a Google Account can create in Sheets, and the app includes native formulas, pivot tables and charts, so a chart can sit next to the numbers it describes and update as they change. Files work on phone, tablet and desktop, can be edited offline, and can be shared with view, comment or edit rights. Google says Workspace, the product family that includes Sheets, has served more than 10 million businesses, which is why we score its adoption high. The limits show once you want more than one chart: there is no dashboard canvas, chart styling is simple, and some Gemini in Sheets features need a paid Workspace plan. Many people keep the data in Sheets and connect it to Google Data Studio for a proper report. We compared documented features and published terms; we did not run hands-on tests.

   Strengths

   • +Free with a Google account, nothing to install
   • +Charts update as the sheet changes
   • +Works as a data source for Google Data Studio

   Limitations

   • −Chart types and styling are basic next to dedicated tools
   • −No dashboard canvas for multi-chart reports
   • −Some Gemini in Sheets features need a Workspace plan

   SummaryGoogle Sheets is the best choice for quick charts from spreadsheet data because charts and pivot tables come free with any Google account. Move to Data Studio or Tableau Public when you need dashboards or maps.

   Datawrapper

   Web tool for making clean, embeddable charts, maps and tables, used widely by newsrooms and public bodies.

   8.5overall

   Web tool for making clean, embeddable charts, maps and tables, used widely by newsrooms and public bodies.

   Best forjournalists, researchers and public agencies publishing charts and maps online

   Datawrapper is the chart maker many newsrooms use, and its case studies include The Philadelphia Inquirer, Aftenposten, KFF and the New York City Department of Health. Its Free plan is unusually generous: Datawrapper says it lets you create, publish, embed and export visualizations as PNGs without limits, and covers interactive charts, maps and tables. It also promises not to sell your data or add tracking code to embedded charts, even for free users. Free accounts get a shared team workspace and 30 days of edit history, and the API includes a free monthly allowance of 500 create, 1,000 publish and 3,000 export operations. Paying removes the Created with Datawrapper credit and adds PDF and SVG export on Pro at $21 per user per month excl. VAT, and waterfall and dual-axis charts on Business at $39. Datawrapper publishes no current user count, so we scored adoption conservatively. It does not build multi-chart dashboards. We compared documented features and published prices; we did not run hands-on tests.

   Strengths

   • +Datawrapper says the Free plan creates, publishes, embeds and exports PNGs without limits
   • +Datawrapper states it will not sell your data or track your readers, even on Free
   • +Maps and tables are included alongside charts

   Limitations

   • −Free charts carry a Created with Datawrapper attribution
   • −PDF and SVG export start on Pro at $21 per user per month
   • −Waterfall and dual-axis charts need the Business plan at $39 per user per month

   SummaryDatawrapper is the best choice for people who publish charts and maps in articles, because its Free plan creates, publishes and embeds without limits. Pay $21 per user per month for Pro only if you need SVG export or to remove the credit line.

   Metabase Open Source

   Open source business intelligence tool for questions, charts and dashboards, free to self-host with unlimited users.

   8.5overall

   Open source business intelligence tool for questions, charts and dashboards, free to self-host with unlimited users.

   Best forstartups with a database and someone who can run a server

   Adoption data

   100,000+ companiesMetabase says on its homepage that it is trusted by more than 100,000 companies.

   Metabase, Metabase homepage (2026): “Trusted by 100,000+ companies”

   Metabase Open Source is the free edition of a business intelligence tool that Metabase says is trusted by more than 100,000 companies. It runs on your own infrastructure and the pricing page lists free unlimited users, unlimited questions and dashboards, more than 20 supported data sources, and both a click-based query builder and a SQL editor. That combination lets people who do not write SQL build their own charts from a company database. The current version also supports asking questions with AI on your preferred model and includes an MCP server. The cost is operational: you install, back up and upgrade it yourself. Metabase Cloud removes that work from $100 per month on the Starter plan with the first five users included, and features such as row and column permissions and SSO sit on Pro at $575 per month. Metabase is a dashboard tool for live databases, not a design tool for one-off charts or maps. We compared documented features and published prices; we did not run hands-on tests.

   Strengths

   • +No per-user fees on the Open Source edition
   • +Non-technical users can explore data by clicking
   • +Can move to Metabase Cloud later

   Limitations

   • −Open Source edition must be installed and maintained on your own server
   • −Row and column permissions and SSO need the Pro plan at $575 per month
   • −Works from databases, not from pasted spreadsheets

   SummaryMetabase Open Source is the best choice for startups that want free self-serve dashboards on their own database, because the self-hosted edition has free unlimited users. Teams without anyone to run a server should consider Metabase Cloud at $100 per month.

   Grafana

   Open source dashboard and visualization tool, strongest for time series and monitoring data, with a free Grafana Cloud tier.

   8.4overall

   Open source dashboard and visualization tool, strongest for time series and monitoring data, with a free Grafana Cloud tier.

   Best forengineers charting metrics, logs and time series

   Adoption data

   10,000+ customersGrafana Labs says it is trusted by over 10,000 customers, from startups to enterprises.

   Grafana Labs, About Grafana Labs (2026): “We're trusted by over 10,000+ customers, from startups to enterprises”

   Grafana is the standard open source choice for dashboards on live, time-based data. Grafana OSS is free to download and run, and Grafana Labs says 150+ plugins let you combine data sources in one dashboard, with visualizations ranging from time series graphs to heatmaps and 3D charts. Dashboards and alerts can be managed as code, and Grafana 12 added Git Sync and SQL expressions. If you would rather not host it, Grafana Cloud has a free tier with no credit card required, limited to 10k active metric series per month and 14 days retention, and the Pro tier starts from $19 per month plus usage. Grafana Labs says it is trusted by over 10,000 customers. For people who want a pretty bar chart for a report or an article, Grafana is the wrong fit: it is designed for monitoring systems and business metrics over time, and it expects you to know your data source and its query language. We compared documented features and published prices; we did not run hands-on tests.

   Strengths

   • +Grafana OSS is open source and free to self-host
   • +Grafana Cloud's free tier needs no credit card
   • +Very strong for live, time-based data

   Limitations

   • −Grafana Cloud Free limits metrics to 10k active series per month with 14 days retention
   • −Built for monitoring rather than presentation charts or editorial maps
   • −Setup assumes familiarity with data sources and query languages

   SummaryGrafana is the best choice for engineers who want free live dashboards of metrics and time series, because Grafana OSS is open source and Grafana Cloud has an always-free tier. It is not built for presentation charts or editorial maps.

   Flourish focuses on interactive, animated charts and maps for the web, and it is now part of Canva. Its Free plan includes unlimited projects, the full range of templates for charts, maps and interactive content, and full privacy for anything you have not published. Flourish lists 50+ templates, from bar charts and interactive maps to Sankey diagrams, data explorers and timelines, and every graphic is responsive. A Flourish Assistant refines charts from plain-language prompts, with a starter allowance on Free. Publishing on the free plan is public and embeds carry Flourish attribution. The Presenter plan comes with Canva Business or Enterprise and adds Canva and PowerPoint embeds plus image and SVG export, while live data from Google Sheets or CSV, scrollytelling and attribution-free website embeds need Publisher, which is sold by quote. Flourish says it is used by thousands of companies every day. We compared documented features and published terms; we did not run hands-on tests.

   Strengths

   • +Full range of templates is available on the free plan
   • +Projects stay private until you publish
   • +Responsive graphics for every screen size

   Limitations

   • −Free embeds show Flourish attribution
   • −Live data from Google Sheets or CSV and scrollytelling need the Publisher plan
   • −No public USD price for Publisher; it is sold by quote

   SummaryFlourish is the best choice for communicators who want animated charts and maps for free, because the Free plan includes every template and unlimited projects. Expect a Flourish credit on free embeds.

   Apache Superset

   Open source data exploration and dashboard platform from the Apache Software Foundation, with 40+ chart types and a SQL IDE.

   8.1overall

   Open source data exploration and dashboard platform from the Apache Software Foundation, with 40+ chart types and a SQL IDE.

   Best fordata teams that want a free, self-hosted alternative to paid BI tools

   Adoption data

   thousands of companiesThe Apache Superset project says thousands of companies use Superset to explore and visualize their data.

   The Apache Software Foundation, Apache Superset (2026): “Join thousands of companies using Superset to explore and visualize their data”

   Apache Superset is an open source data exploration and visualization platform maintained under the Apache Software Foundation. It ships with more than 40 pre-installed visualization types, from simple line charts to detailed geospatial charts, and a plug-in architecture for building your own. Users can work in a no-code chart builder or in SQL Lab, which supports custom queries, metadata browsing and Jinja templating. Dashboards support cross-filters, drill-to-detail and drill-by, and CSS templates let you match your brand. Superset connects to any SQL-based database and sits on top of your existing data stack rather than copying data into its own store. The project says thousands of companies use it. Because it is free software rather than a hosted service, you are responsible for installation, security and upgrades, and there is no vendor support desk. It is best for teams that already keep data in a SQL database and have engineers to run it. We compared documented features and published terms; we did not run hands-on tests.

   Strengths

   • +Free under the Apache License with no user limits
   • +Geospatial charts are built in
   • +Works on top of existing databases without a separate ingestion layer

   Limitations

   • −You must install, secure and update it yourself
   • −Needs data in a SQL database, not spreadsheets
   • −No vendor support on the open source project

   SummaryApache Superset is the best choice for data teams that want a free, self-hosted BI tool, because it ships 40+ chart types under the Apache License. Teams without engineers should pick a hosted free tool instead.

    RAWGraphs

    Free, open source web app that turns spreadsheet data into vector charts you can finish in a design tool.

    7.5overall

    Free, open source web app that turns spreadsheet data into vector charts you can finish in a design tool.

    Best fordesigners who want unusual chart types as editable SVG

    RAWGraphs is a free, open source web app led by the DensityDesign Research Lab at Politecnico di Milano together with the studios Calibro and Inmagik, first released publicly in 2013. It is meant as a bridge between spreadsheet apps and vector graphics editors: you paste or load a table, pick one of almost 30 visual models for quantities, hierarchies and time series, and export the result as a vector or raster image to finish in Illustrator, Inkscape or Figma. Although it runs in a web browser, RAWGraphs says the data you insert is processed only by your browser, which suits sensitive figures. You can save a project to come back to it. What it does not do is host interactive charts, build dashboards or connect to live data, so it is a design tool rather than a reporting tool. The project publishes no user figures, so we scored adoption low. We compared documented features and published terms; we did not run hands-on tests.

    Strengths

    • +Free with no account needed
    • +Your data stays in the browser
    • +Vector output opens in Illustrator, Inkscape or Figma

    Limitations

    • −Static exports only, with no dashboards or hosted embeds
    • −Smaller project with no published user figures
    • −No live data connections

    SummaryRAWGraphs is the best choice for designers who want unusual charts as editable vectors, because it is free and keeps data inside the browser. Use another tool for interactive or live charts.
