In part 4 of this series on analyzing data with XSLT, the MindMap Research Team realized that the cognitive data they're analyzing might be easier to understand if represented in the 3D space for which it is intended. The team decides to use XSLT to transform it into a 3D graph so changing the viewpoint changes the view of the data. This tutorial shows how to implement this from a command line and using a browser to display the results.
