Theinformation visualization technique used by Trendalyzer is an interactivebubble 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 usesbrushing and linking techniques for displaying the numeric value of a highlighted country.

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[1] ).
