3D Petersen Graph

A graph is a collection of vertices and edges. 3D graphs are useful in visualizing particular 3D data sets.
This graph is a common example of a graph known as a Petersen graph. It has had several vertices pulled out into the 3rd dimension to avoid any crossings that would normally be present if it was only displayed in two dimensions.
This graph was generated using the "Graph to STL" plugin for GLuskap, a piece of graph drawing software (available here: https://github.com/ulethHCI/GLuskap). The last image shows the graph as it appears in GLuskap, and how it appears as a printed model.
