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, …).

RAWGraphs 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 injected into RAWGraphs 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!

RAWGraphs 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.


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


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



Clone RAWGraphs from the command line:

$ git clone

browse to RAWGraphs root folder:

$ cd raw

install client-side dependencies:

$ bower install

add analytics script:

$ cp js/analytics.sample.js js/analytics.js

open the file js/analytics.js and add your analytics code (if any), otherwise leave the file as is.

You can now run RAWGraphs 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 RAWGraphs can be found on the wiki.


Information about the available charts can be found here. Adding new charts is very easy in RAWGraphs, 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.


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