Encyclopedia
Trendalyzer is an information visualization
software for animation
of statistics
that was initially developed by Hans Rosling
's Gapminder Foundation
in Sweden. In March 2007 it was acquired by Google Inc.. The current beta version is a Flash
application that is preloaded with statistical and historical data about the development of the countries of the world.
The information visualization
technique used by Trendalyzer is an interactive bubble chart
. By default it shows five variables: Two numeric variables on the X and Y axes, bubble size and colour, and a time variable that may be manipulated with a slider. The software uses brushing and linking
techniques for displaying the numeric value of a highlighted country.
Some components of the Trendalyzer software, particularly the Flash-based Motion Chart gadget, have become available for public use as part of the Google Visualizations API (see http://code.google.com/apis/visualization/documentation/gadgetgallery.html ).
