Graph Theory Tutorial

Normally it is supported by two vertices.

Digraph Online

You can play with the online digraph below

How to use?

  • Click in the open space to add a vertex, drag from one vertex to another to add an edge.
  • Ctrl-drag a vertex to move the graph layout.
  • Click a vertex or an edge to select it.
  • When a vertex is selected: type R toggles reflexivity, use Delete button in your keyboard to remove the vertex.
  • When an edge is selected: L(eft), R(ight), B(oth) change direction, Delete removes the edge.
