A visualisation of change over time

The change concept of the Australian Curriculum: Geography can be brilliantly demonstrated by visualisation videos and Infographics showing change over time. Here are just  a few.

* 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 blog.dwtkns.com/2011/posted/ 


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. 

* Watch the world get older

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.

Global Climate Change visualisation

A video data visualisation showing the change in temperature across the world over the last 200+ years. It is based on the data released by the UK's Met Office in Dec 2009.
