Visualizing the Entire U.S. Judicial System - How High the Mountain

I have been on a quest to create a visualization of the entire US judicial system.

So far, I've gathered enough information to do this for the federal courts, and the state appellate courts. This includes about 400 courts. Here's a screenshot of that (the interactive visualization is available at

There are lots of other courts within the states, of course, and diving into that is next on my list.

I came across the National Center for State Courts web site that has, among other things, a count of the number of courts within the states. This includes circuit courts, district courts, municipal courts, probate courts, and even "Town and Village Justice" courts in New York. I am not sure exactly how accurate these numbers are, but it provides some perspective as to how big the total number is.

The figure below provides some insight into how much farther I've got to go with this visualization:

includes only the courts in that little green wedge.

"Interactive State Court Organization App",

Whatever the precise numbers are, it is clear that there's a ways to go here.
