The plan of a flowchart of Pele
| Part | data-id | Name |
|---|---|---|
| A node | web | web |
| A subgraph | app | app |
| An edge | L_web_api_0 | web->api |
| A second edge between the same ends | L_web_api_1 | web->api:2 |
An edge with an id in the source, such as web e1@--> api | e1 | e1 |
The ends of an edge and the members of a subgraph come from the model,
because an id such as L_web_ui_api_0 cannot give its ends safely. The
arrow is <-> for an edge with a head at each end, -- for an edge with no
head, and -> for each other edge. The group of the label of an edge has
the class pele-edge-label, so it takes the name of its edge and no marks.
A swimlane diagram and an agent flow have the model of a flowchart, and a lane or a flow is a subgraph, so this plan names their parts too. Pele draws a collapsed flow of an agent flow as one node, with no group for its members, so an edge to a member has the flow as its end.
