§Graph Drawing and Visualization

This module is intended to provide utilities for visualizing graph structures, primarily by generating Scalable Vector Graphics (SVG) outputs. It aims to facilitate the visual inspection and analysis of graphs represented within the linnet library.

Currently, the module’s direct public API for drawing HedgeGraph instances is not yet fully exposed or implemented. The existing code includes examples and tests demonstrating the use of the kurbo crate for creating and manipulating 2D Bézier paths, and serializing these paths into SVG format.

Future development in this module will likely focus on:

  • Providing functions to take a HedgeGraph and produce an SVG representation.
  • Integrating layout algorithms to position nodes and edges aesthetically.
  • Offering customization options for styling the output (colors, stroke widths, etc.).

Users interested in path drawing can look at the internal tests for examples of using kurbo::BezPath and its SVG export capabilities. For direct HedgeGraph visualization, the DOT output functionalities (see dot_parser module and HedgeGraph::dot_... methods) can be used in conjunction with external Graphviz tools.
