Creating Google Maps with Google Maps Data API

Google Maps Data API allows creating maps programmatically.
Using JavaScript and Ruby I extracted data from Wikipedia page List of cities proper by population and created Google map from this data.
Google Geocoding Service was used to retrieve coordinates of the cities.

Click on the image below to open the map and see 61 the most populous cities of the world.
