A graph is a collection of vertices and edges. 3D graphs are useful in visualizing particular 3D data sets.

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).

This graph was printed on medium resolution on a Makerbot Replicator 2, with supports and a raft. The raft and supports were removed after printing with a pair of needle nose pliers.
