## rex_graph

**Usage**

**Build graph**

Sample capx

Call "Action:Add edge" to add an edge and two connected vertices, or call "Action:Add vertex" to add a vertex. Each edge or vertex is an instance basically.

**Test connections**

Get connected vertices or edges by "Action:Pick vertices of edge" or "Action:Pick edges of vertex".

**Pick vertices**

Sample capx

Get neighbor vertices by "Condition:Pick neighbor vertices". Or get all connected vertices by "Condition:Pick all connected vertices".

**Closed loop**

Sample capx

"Condition:In closed loop" will return true if a vertex is in a closed loop (cycle).

**Adjacent**

"Condition:Are neighbors" will return true if there has any edge between these two vertices.
