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

Answer 1

In addition to Graph::Easy mentioned by @nibot, there are a couple of other tools around for this:

• Vijual (Clojure): http://lisperati.com/vijual/
• ascii-graphs (Scala): https://github.com/mdr/ascii-graphs

(Disclaimer: I'm the developer of the latter).

Answer 2

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

Here's some output from the online demo:
