Raw is an open web tool developed at the DensityDesign Research Lab 
(Politecnico di Milano) to create custom vector-based visualizations on 
top of the amazing d3.js library by Mike Bostock. 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 delimiter-separated values (i.e. csv and tsv files) 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 
operation or storage is performed and no one will see, touch or copy 
your data!

Raw is also highly customizable and extensible, accepting new custom 
layouts defined by users. For more information about how to add or edit 
layouts, see the Documentation section.
