DTrace Treemaps

This is an ongoing experiment to visualize the output of some DTrace scripts. This one is called js_functime.d. The output being analyzed is available here.

Each tree is grouped by file, and contained within, the functions.

Remember: This page may not be permanent and the work isn’t anywhere near done.
Where'd the data come from? I think this was during startup, but don't focus on that just yet.
SVGs are 1920x1107 (optimized for my monitor), so they may be a bit big unless you maximize & get rid of menus.
