Dash is short for dashboard. This shows several visuals for geographic data: wiggle map, time series, MDS & a table.
To set up as developer you will need to use npm to retrieve package dependencies like wiggle maps.
To use npm, you'll need to install node (http://nodejs.org/). On a mac you'll also need the xcode command line tools if you don't have it already.
Once npm is installed, run npm install in dash to download the dependencies.
