Markov Chain Maker

Create states, draw weighted transitions, and repair rows explicitly.

Select one or more source states, then use Transition mode and click a target state to add transitions.

Probability

Continuous normalization for newly added transitions

When enabled, a new outgoing transition receives an equal share from each current outgoing transition. Empty rows are treated as an implicit self-loop of 1, so the first added edge gets probability 0.5.
