I have developed a new experimental interactive app for exploring the United States Constitution.

This app allows you to navigate the contents of the U.S. Constitution while displaying the overall hierarchy and structure. You can click on the various Articles and Amendments to expand the sub-parts and and see the accompanying text.

This app was somewhat more challenging to develop because I was unable to find any version of the U.S. Constitution that had been written in .xml.  Thus, I had to create an .xml version of the Constitution myself.  In a follow-up post, I will include the xml version of the U.S. Constitution

This app was created using the d3 data visualization framework and javascript.  It uses Mike Bostock’s collapsible tree framework as a base.
