Tell your data story with free and easy-to-learn tools.

Data Visualization for All, an open-access textbook, shows how to design interactive charts and maps for your website.

This friendly introduction includes step-by-step tutorials, video screencasts, and real-world examples. Featured tools include Google Sheets, Tableau Public, Highcharts, Leaflet, GitHub, and more.
