A function's source code next to it's control-flow-graph. The graph has yellow notes on it, surrounding some of the nodes. In the source code, there are comments matching the notes instructing the tool where to place them and what to write in them.
Added the overlay-note-region-name-pending feature to the demo behind a feature-flag.
You can play with them at tmr232.github.io/function-gra...
Use `cfg-overlay-start: message` and `cfg-overlay-end` comments to denote the start and end of a region.
