Moving Vertices and Edges

   

The <1st> button is used to move vertices and edges around. To move an edge, make sure that the edge label is visible. This label is also the control point of a cubic spline, so that when you drag it around, the edge is pulled into an arc. This is necessary for visualizing multigraphs, and generally useful for improving the appearance of drawings.
