1. Tableau Public

Tableau Public is a free tool that allows for easy data visualization. What more can you want?

With a massive arsenal of maps, graphs, and charts, it is a firm favorite for the non-developer audience.

As a free data visualization tool, Tableau Public has some limitations. For example, Tableau Public limits saving locally and refreshing data. Any visualizations published are also accessible to the public, so don’t use Tableau Public for private data.

Take a look at their gallery to understand what Tableau can do for your data visualization projects.

2. Google Data Studio

4. Datawrapper

Datawrapper is an extremely easy-to-use data visualization software for charts, maps, and tables.

5. D3

D3 — also known as D3.js — is a JavaScript library that uses HTML, SVG, and CSS to visualize data.

With D3, developers can create even the most complex charts and graphs. Since D3 uses open web technologies (HTML, SVG, and CSS), you get great cross-platform support with this data visualization platform since web browsers and smartphone apps can all run these web technologies.

A few features of D3 to know include its design. D3 is designed for modern browsers. It won’t work with any browser before Internet Explorer 9. If someone does view your visualizations on an older browser, there will likely be compatibility issues.

Another thing to consider is that D3 will require you to learn the D3 API. However, D3 can be an insanely powerful data visualization tool in your marketing toolkit once you know how to use it.

D3 is an open-source project. Be sure to check out this gallery of D3 examples.

Even better, RAWGraphs will keep your data secure since the browser only processes data!
