View source for Platonic solid graph generator

Wandora's platonic solid graph generator creates algorithmically graphs for simple geometrical objects known as [http://en.wikipedia.org/wiki/Platonic_solid Platonic solids]. Generated graphs are compositions of topics and associations. Topic is a graph node or vertex in Topic Maps lingo. Association is a graph edge. You may think the generated topic maps as graph abstractions of real geometrical objects. Platonic solids are

* [http://en.wikipedia.org/wiki/Tetrahedron Tetrahedron]
* [http://en.wikipedia.org/wiki/Cube Cube]
* [http://en.wikipedia.org/wiki/Octahedron Octahedron]
* [http://en.wikipedia.org/wiki/Dodecahedron Dodecahedron]
[http://en.wikipedia.org/wiki/Icosahedron Icosahedron]

Wandora's platonic solid graph generator starts with menu option '''File > Generators > Platonic solid graph generator...'''. First Wandora opens up a dialog window used to select which platonic solid is created. Screen capture below views the platonic solid selection window.

Generator creates a topic for each vertex and connects the vertex topic to other vertex topics sharing an edge. Generator names vertex topics with a base name

 <object> Vextex <n>

where <object> is '''Tetrahedron''', '''Cube''', '''Octahedron''', '''Dodecahedron''', or '''Icosahedron'''. and <n> is a number of the vertex. First vertex gets number 0. For example, '''Cube Vertex 5''' is a base name for cube's last vertex topic. Similarly each vertex topic is given a subject identifier

 http://www.wandora.org/<object>/vertex<n>

where <object> is a '''lower case''' name of the object and <n> a number of the vertex. Vertexes are connected with edge associations. Association type's base name and subject identifiers are

  <object>Edge
  http://www.wandora.org/<object>/edge

Association roles are

  <object> Role 1
  http://www.wandora.org/<object>/role1

  <object> Role 2
  http://www.wandora.org/<object>/role2

If you are not happy with default roles you can apply Wandora's topic manipulation tools to change the topic after graph creation.
