What is Contour?

Forio Contour lets you create data visualizations easily, based on intuitive abstractions commonly used in charts and graphs. Contour provides a core set of common visualizations that you can see in our gallery, and it’s easy to extend if you want to add your own customizations.

Forio Contour provides a core set of common visualizations that you can see in the gallery, and it's easy to extend if you want to add your own customizations. Plus, it's free and open source.

A big part of our work at Forio involves creating data visualizations for models and simulations. While many excellent plotting and graphing libraries already exist, we decided to take what we’ve learned over nearly a decade of data visualization work and create our own.

Forio Contour uses the popular D3 engine and adds a set of intuitive abstractions so you can easily create graphs and charts.
