The other day I was seeing this nice presentation by Hans Rosling where he is presenting the different statistics of the developing world and how they changed over time. See his other talks on various topics.
I was largely impressed by the tool that he used in the presentation. It has a great visual appeal. It can represent different dimensions at the same time in the 2-D chart. Other than the regular X,Y axis it uses color, size, time to represent the other dimensions. The way one can drill down further into the statistics in a visual manner is very nice.
The software tool is developed by him and his colleagues at his non-profit organization "Gapminder". It was initially called Trendalyzer. Then google later bought this tool when the google founder saw this TED talk and was impressed by the software. Now, this software is available as a free gadget in spreadsheet in online google docs. Here is a tutorial on how to use this tool in google spreadsheet. Here is one more tutorial.
