%% Demonstrates the physics debug/... family of keys.
%% The key is cascadable: works at tikzpicture, scope, or node level.

%%   physics debug/anchors = true    numbered dots + legend table
%%   physics debug/keys    = true    accepted keys box
%%   physics debug/all     = true    both of the above
