## Creating Vertices and Edges

Graphs can also be created using the mouse. Clicking the <3rd> button on the canvas creates vertices, and clicking the same button on two vertices in sequence creates the appropriate edge. If the graph is a variety of hypergraph, then edges containing more than two vertices. This is accomplished by clicking <3rd> on the first vertex of the edge, <Shift-3rd> on all intermediate vertices, and finally clicking <3rd> on the last vertex.
