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 operations or storages are 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 Developer Guide.

##Usage The easiest way to use RAW is by accessing the most updated version on the official app page. However, RAW can also run locally on your machine: see the installation instructions below to know how.

##Installation If you want to run your instance of RAW locally on your machine, be sure you have the following requirements installed.



Clone RAW from the command line:

$ git clone git://

browse to RAW root folder:

$ cd raw

install client-side dependencies:

$ bower install

You can now run RAW from your local web server. For example, you can run Python's built-in server:

$ python -m SimpleHTTPServer 4000

or for Python 3+

$ python -m http.server 4000

Once this is running, go to http://localhost:4000/.

Troubles with the installation? Maybe a look at the issues page can solve your problem, otherwise join the Google group.

##Documentation and Support

Documentation and FAQs about how to use RAW can be found on the wiki.


Information about the available charts can be found here. Adding new charts is very easy in RAW, see how here!

If you have any suggestion or request about new layouts to include, please let us know! If you have already created new charts and you would like to see them included into Raw, please send us a pull request.


RAW has been developed using a lot of cool stuff found out there:

jQuery UI Touch Punch


  • Refactoring using reusable charts as layouts
  • Introducing continuous color scales (for numeric values)
  • Mobile support
  • Improving documentation and API Reference
  • Creating and exporting legends
  • PDF export
