Recently I created two different interactive apps visualizing and exploring the Titles of the U.S. Code. You can browse the text of Title 35 (Patent) and Title 17 (Copyright) in a visually interesting manner. Click on the photos below to use them.
Tree Layout Visualization
Force Directed Graph Visualization
D3, Javascript, .xml
These layouts were created using the d3 data visualization framework, javascript, and xml. They take advantage of the fact that the Titles of the U.S. Code have been released in .xml.
