The Factmint Researcher was used to create a collection of heat-maps for the Guardian Data Blog’s London: The Data series. The heat-maps, which used open-data around the 2008 Mayoral Election, were used to demonstrate the voting tendencies for different geographic and social areas.
The visualization proved very popular with Guardian readers, most read on the UK News section and top of the “Zeitgeist” for most of the 24 hours after it was published.
