Mapping the 300 Million
The Census Dotmap is an amazing map showing the location of every American counted in the 2010 national census. The map contains 308,450,225 dots, that is one dot for every American.
The map can easily display that many dots as the plotting was completed using Python and the resulting image converted into map tiles. The tiles are then displayed using the Custom Maps Type of function of the Google Maps API.
The result is a beautiful map that shows the population of the USA uncluttered by the standard map features of city boundaries, arterial roads, state lines etc.
