Index of Module graph

Module: graph

The graph module is a Scheme-based implementation of the public domain C-Graph vector plotting library. It is intended for generation of scientific graphs. The engine is designed to support multiple output backends. Currently only PDF is implemented.

Simple examples of usage can be found in modules/graph/examples.
