Task graph, live: what runs in parallel & the critical path
Each box is a task; the number is how long it takes. An arrow A→B means
B needs A's result. Press Run and watch tasks light up as they
finish — independent tasks light up together. The glowing chain is the
critical path: the longest run of dependencies, which sets the fastest
possible finish time.

Press Run to watch it execute. Notice the four middle tasks start at the same instant — that's the parallelism the graph exposes.
