Using Hover Interactions with Google Maps
Population change from 2010 to 2011 is a chloropleth map showing the percent change in population of all 159 Georgia counties between 2010 and 2011.
It is possible to mouse-over each county on the map to view the data for that location. The map creator, Carl V. Lewis, discusses the advantages and disadvantages of using mouse-over interactions on Google Maps in his article Making the Case for Hover Interactions in Maps.
Carl is a journalistic web developer and his blog covers a number of interesting articles covering various aspects of data visualisation in journalism.
