Free Tools for Data Visualization

Visualizations are graphical representations of information, data or knowledge. It helps us to quickly grasp complex relationships and see patterns. This is the reason why infographics has become so popular. It’s also become a great way for businesses to tap into the power of data visualization.

According to Wikipedia, data visualization is the interactive visual representation of data. Data visualization is an alternative to data analysis and is closely related to statistical graphics and information visualization. Data visualization it makes it easy to identify patterns in huge quantities of information. Best of all, data visualization has grown in popularity and more developers than ever before are providing freebies for you to use on your website.

Data visualization is a way to communicate data or information in a graphical manner. Visual representations of data make it easier to understand and analyze the data. Data visualizations show relationships between variables quickly and efficiently, as opposed to process of extracting information from tables or text files.

Tableau Public

This is right at the top because it’s essentially the same platform as our self-service BI tool Editors’ Choice winner Tableau Desktop . The company chose not to make its free version feature-poor. Instead, this is the full version of Tableau that’s available for free download, with only one caveat: Everything you create with it is public, which means you’ll automatically be making it available on the web via Tableau’s visualization gallery.

Pro: Tableau Public is that it offers unparalleled data visualization with fully functional and interactive graphics.

Con: You cannot save your workbook locally and everything you create gets shared publicly on your Tableau Public profile, which limits its usefulness for work based on proprietary data.

Tableau Gallery

gallery is cool enough to warrant a mention all its own because you don’t need to download the tool nor use it to benefit from the gallery. Every visualization here can be downloaded into documents and email, or embedded into webpages with code snippets provided by Tableau. Other folks have done tremendous work on some truly impressive data visualizations and Tableau has curated that content and made it available for download. This is a great resource, not only for business people but also for researchers, students, and journalists looking for ways not just to flesh out and beautify their content but to keep it current, too.

Google Data Studio

Part of the Google Marketing Platform, Google Data Studio lets users build multiple views of their data as well as dashboards rather than one-time, publication-ready visualizations. While it follows the Google tradition of requiring somewhat of a learning curve, it’s nevertheless not that difficult to use. It’s also well integrated with Google Analytics , which can make for quite a powerful pairing—especially since both tools are available in free-to-play versions.


This one purports to transform your spreadsheet, presumably encumbered with some kind of geographical data, into a functioning heat map with just one click. It works with Google Spreadsheets so you’ll have to import your Microsoft Excel spreadsheet there if you want to use Openheatmap. But that’s a relatively trivial requirement considering the possible results.

Flourish Public

When it comes to storytelling, Flourish tops the list and is ideal for anyone looking to tell stories with data. It enables immersive storytelling rather than more traditional ways of visualizing as tables, diagrams, and dashboards. Unlike Tableau Public, Flourish does not require a desktop edition. It is browser-based. You can choose a wide range of flexible templates from the library. Flourish is typically for social media sharing and website content.
