RAW is an open web tool to create custom vector-based visualizations on top of the amazing d3.js library.

Primarily conceived as a tool for designers and vis geeks, RAW 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, …).

RAW works with tabular data (e.g. spreadhseets and comma-separated values) as well as with copied-and-pasted texts from other applications (e.g. Microsoft Excel, TextWrangler, TextEdit, …). Based on the SVG format, visualizations can be easily edited with vector graphics applications for further refinements, or directly embedded into web pages.

Knowing the need of working with sensitive information, the data uploaded to RAW is processed only by the web browser: no server-side operations or storages are performed and no one will see, touch or copy your data!
