Application in graph theory

In graph theory, models and drawings often consist mostly of vertices, edges, and labels. So, it may be possible to use a simpler language to generate a diagram of a graph.

How to do it...

The tkz-graph package offers a convenient interface. We will create a diagram with it as follows:

  1. Begin with any document class:
    \documentclass{standalone}
  2. Load the tkz-graph package:
    \usepackage{tkz-graph}
  3. Specify a basic style:
    \GraphInit[vstyle = Shade]
  4. Customize element styles as desired using standard TikZ syntax:
    \tikzset{ LabelStyle/.style = { rectangle, rounded corners, draw, minimum width = 2em, fill = yellow!50, text = red, font = \bfseries }, VertexStyle/.append style = { inner sep=5pt, font = \Large\bfseries}, EdgeStyle/.append ...
