From a CSV which you can download from the [AEC](http://www.aec.gov.au/) generate a GeoJSON file containing locations of polling places in your electorate. See example output for the [Melbourne electoral division](http://www.aec.gov.au/profiles/vic/Melbourne.htm). Note, the script needs [Requests](http://docs.python-requests.org/en/latest/) to r…

"""
Where is my polling place?
==========================
Simple script to call the Google Geocoder service and get a map of polling
places. View the locations in Google Maps by converting the outout GeoJSON to
KML (Use ogr2ogr or `Jason Sanford's geojson-google-maps
<https://github.com/JasonSanford/geojson-google-maps>`_ utility) .Note that
the Google TOS require that the results of the geocode are used to be viewed
in google maps.
Built using `requests <http://docs.python-requests.org/en/latest/>`_ which you
should install if you want to use this.
