Patrick Ng seems to be the inventor of a chronodex visual planning system. His website has half yearly printable planner inserts for Midori's Traveler's Notebooks.

One of his downloadable templates reads:

Chronodex ideas and notations are copyrighted, it is free for personal use, please contact Patrick Ng (patrickng@mac.com) for commercial usage.

Examples of chronodex layouts on his website show his uses which also seem to include some sketchnoting usage as well.
