* Visualisation of US expansion in North America from 1700 to 1900, seen through changes in the spatial distribution of post offices. The data from the USPS Postmaster Finder, with lat/long coordinates extracted from placenames through correlation with the USGS Geographic Names Information System.There is also an interactive version of this map.  More can be found at 

Many twitter users reply to their friends' tweets. When both the original tweet and the reply include location data, we can show the connections. The result is a depiction of the replies spanning the globe during one day.

The graph shows how, over the course of a century, Japan shifts from a nation where
children predominate to a nation of senior citizens.

A very interesting infographic using words to show change of focus with Presidential speeches.
