DotMat is a free-to-use, mobile responsive data visualization tool. It is useful for communicating part-of-the-whole relationships. It illustrates how one individual item, such as one person or one company, fits into larger trends. The tool allows journalists to add a narrative alongside their visualization to add context.

It's quick and easy to create your own visualization. Plug your data into a Google Sheet and connect it to DotMat. The fonts, headers and colors can be customized to match your publication's style.  

The inspiration for DotMat came from FiveThirtyEight's "Gun Deaths in America" project, which displays the demographics and causes of all gun-related deaths in the U.S. from 2012-2014." Instead of using bar or pie charts to present summary data, this project used very small dots to represent each individual killed.
