Whether you've realized it or not, D3 has been driving many of the most compeling data visualizations that you have likely seen throughout the last year including a popular series of election tracking tools in the New York Times.
You can find a series of examples in D3's gallery that will keep you busy for hours!
In addition to the fantastic charting tools, D3 also enables a growing list of mapping capabilities. It is really exciting to see where all this is heading.
