Great Example of Multi-dimensional Bubble Chart

Here is a beautiful example of a bubble chart display using global population statistics. The example on carbon emissions are very interesting. Note the dimensions
  1. Population of County (size of bubble)
  2. Continent (color of bubble)
  3. Live Expectancy (vertical axis)
  4. Income (horizontal)
  5. Time (the play button)
It is interesting to see the huge impact AIDS has had on the life expectancy in African counties. Imagine if you could see your organizations product sales using this type of graph. This application was done with a software system called Trendalyzer. It was initially developed by Hans Rosling's Gapminder Foundation in Sweden and acquired by Google Inc. in March 2007. This version is a Flash application. Does anyone know of any open-source software that could do this?
