protovis part 5: swap external data


It's time to use what we learned it the previous tutorials. In this Protovis tutorial, we're going to change the bar chart that we made in the last tutorial into a line chart, swap external data files and build on the existing graphic. We're also going to use an animation technique to make it easier for users to interact with small visual elements like lines.

By the time you're done with this tutorial, you should have a deep enough understanding to customize your own visualizations. A written version of this tutorial will be available soon.
