Just to expand on the switching of axis. It's harder to compare data between graphs, but upon second inspection, it appears the colors from the first graph are not used in the secondary graphs.

Second, trying to get to the projects in the first graph, it's easier to exit the graph from the bottom. Otherwise, short bars (eg. node) are hard to "select" for the "Current" line, and in that case, I have to make a longer trip around the graph to get to the link. Maybe link the labels? Move the "Current" line underneath?

I enjoyed it nonetheless. If you're considering expanding or having a follow-up piece, I'd enjoy combining the three graphs with the format / filtering at http://www.techempower.com/benchmarks/.
