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. 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.
