RAW

Currently in beta.

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, 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 imported in and 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 are performed - 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.

##Usage The easiest way to use Raw is by accessing the most updated version on the official app website. However, as an open source Node.js/Express app, Raw can also run locally on your machine.

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

###Requirements

• git
• Node.js
• Bower

Clone Raw from the command line:

$ git clone git://github.com/densitydesign/raw.git

browse to Raw root folder:

$ cd raw

install server-side dependencies:

$ npm install

run server:

$ npm start

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

##Documentation and Support

Documentation and FAQs about how to use Raw can be found on the official website. Development guide will be available soon on the Wiki of this repository. Sorry for this.

##Layouts

Currently, the following layouts are available:

• Treemap
• Bubble Chart
• Circle Packing
• Dendogram
• Circular Dendogram
• Hexagonal Binning
• Alluvial Diagram (Fineo-like diagram)

…and these will come soon:

• Parallel Set
• Area Graph (Lee Byron's Streamgraph-like)
• Horizon Chart
• Convex-hull Scatterplot
• Parallel Coordinates
• Gantt Chart

…and these will come someday:

• Ribbon Streamgraph
• Scatterplot Voronoi Tesselation

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

##Libraries

Raw has been developed using a lot of cool stuff available out there:

angular.js

##Roadmap

• Improve documentation and API reference
• Introducing continuous color scales (for numeric values)
• Creating and exporting visualizations' legends
• PDF export
• Code refactoring using reusable charts as layouts
• labels based on data
