This is an experimental visualization of the US Constitution using a collapseable tree layout. You can click on the individual Articles, Sections, and Amendments to reveal the sub-parts below. The text is displayed in the section to the right.

You can expand or collapse any level. Click on the circle in the upper left hand corner to "focus" a section, hiding all others. Click again to unfocus.

This demo was made using the d3 data visualization framework and javascript.

Other data visualizations of the law that I've created are available here.

Please Note: This visualization is a beta and has not been thoroughly tested. Please do not rely on the laws or the code being error free.

This is a modified version of Mike Bostock's collapsable tree layout.
