Don’t have a coding background? That’s completely alright. With Chartbuilder’s intuitive web-based application, creating charts and diagrams is a matter of copy and paste.

Upload a CSV file or even a Google Spreadsheet and Charted will automatically generative an interactive visualization.

It’s difficult to tell a story well when your reader can’t distinguish different data points. This is where ColorBrewer’s dashboard comes in.

By providing options for colors and styles painted on a complicated map graph, ColorBrewer gives you the chance to experiment and make informed decisions on your data visualizations. It may seem confusing at first, but invest some time and it may become a useful addition to your toolbox.
