Tool to create ASCII graph from a set of vertices and edges?

Question

Is there a tool that takes as input a series of vertices and edges, and outputs a graph in ASCII/Unicode format?

Thanks, Kevin

Yes! Perl has Graph::Easy, as described in this Hacker News comment.

Here's some output from the online demo:

........     +---------+     +-----+

:......:     +---------+     +-----+
               H
               H train
               v
