RAWGraphs is an open web tool to create custom vector-based visualizations on top of the amazing d3.js library by Mike Bostock. It has been developed by DensityDesign Research Lab (Politecnico di Milano) and Calibro, and sustained through a corporate stewardship by ContactLab. Primarily conceived as a tool for designers and vis geeks, RAWGraphs aims at providing a missing link between spreadsheet applications (e.g. Microsoft Excel, Apple Numbers, Google Docs, OpenRefine, …) and vector graphics editors (e.g. Adobe Illustrator, Inkscape, …).
