This is a demonstration of how to create a combination town/county map from a shapefile using TopoJSON and d3.js.

It includes a simplified version of the code used for the Massachusetts special Senate election results on The Huffington Post.

Get the data

Download a shapefile of Massachusetts towns from the state's GIS site:

wget http://wsgw.mass.gov/data/gispub/shape/census2000/towns/census2000towns_poly.exe

# Ember defines function() {}.property() as a shortcut
# for making computed properties
name: (->
  @get('firstName') + " " + @get('lastName')
).property('firstName', 'lastName')

# It is a shortcut to wrapping the function inside
# Em.computed. However, using the "long way" is
# actually a bit nicer in coffeescript due to not
# requiring the parentheses
