If you are at all follow the work of Tim Berner-Lee (the father of the World Wide Web), you are aware that Web 3.0 is going to be all about data. He has been encouraging everyone to upload any data they posess to the internet. Data should not be locked away in some private facility, but rather freely available to enhance the research and development of our world.
Gapminder would make Sir Berners-Lee proud! Founded by "Ola Rosling, Anna Rosling Rönnlund and Hans Rosling" (yes, you have probably seen his TED Talk), Gapminder has collected global data and made it so the information can be assessed visually. The project was originally developed to enhance their Trendalyzer project which has since been bought out by Google and I believe was turned into the Google Motion Chart Gadget. Gapminder continues to keep their statistical tools content current making time series motion graphs freely available through Gapminder World and Gapminder countries.
While you can't add your own data easily, there is enough here for any research project. Select your primary data from their database and and you will be presented with a motion graph that charts the data over time. Select a second database for the other access and you have an even more powerful visual. See this example: www.bit.ly/roCRaC displaying the Literacy rate of males over the age of 15 compared to percent of land area. There are almost 500 data sets to mix and match at Gapminder! They also have a teacher section that is full of ideas and resources. So mind the Gap! And if your all about data visit Gapminder today.
