A weighted, branching multi-stage flow diagram rendered as ASCII density bands instead of colour ribbons. Clicking a node isolates every ancestor and descendant on its path: the surviving nodes and bands re-stack from scratch using only the isolated subset's values, so they genuinely grow to fill the space rather than the rest just dimming.
