I want to create math font inside of my vertex circles, AND draw edges between them. How I typically create network graphs is as follows:


\Edge[label= 20](B)(C)

However, if I do the following, it doesn't work. How can I get around this so that I can have equations or math font inside my nodes and connect them with an edge?

\Edge[label= 20]($2^n$)($t$)

The letters in the first examples serve as node labels hence referencing them needs text chars/numbers. If you want to put other types of labels you need to use L=<special chars> options. If L= option is empty the node label automatically becomes the visual label.


\Edge[label= 20](B)(T)

Also see the manual page 21 for [Math] option and \SetVertexMath switch. – percusse Jan 29 '13 at 2:35
