Graph::easy lets you generate graphs consisting of various shaped nodes connected by edges (with optional labels).

it can read and write graphs in a varity of formats, as well as render them via its own grid-based layouter. it has export filters for graphviz, vcg (visualizing compiler graphs), gdl (graph description language) and graphml. import filters are for graphviz, vcg and gdl.

since the layouter works on a grid (manhattan layout), the output is most useful for flow charts, network diagrams, or hierarchy trees.

graph::easy has an easy-to-understand, compact and human readable graph description language.
