 GRAPH UTILITIES PACKAGE SYMBOL

# GraphCoordinates3D

 calculates a visually appealing 3D layout of the vertices of a graph g and returns the coordinates of the vertices.
• returns the coordinates of the vertices as computed using a graph drawing algorithm in 3D. It is useful when the coordinates of the vertices are needed, rather than a drawing of the graph, or when one needs to draw a graph repeatedly using the same layout but different style.

• This plots a graph:
 Out[3]=
• This gives the coordinates of the vertices in the previous drawing:
 Out[4]=
• This plots the graph with two different styles, using the layout already calculated:
 Out[5]=
• The relationship between vertices and coordinates is given by the following:
 Out[6]=
This shows a drawing of a small graph, and the coordinates associated with the drawing:
This shows the relationship between vertex labels and their coordinates:
The coordinates can be reused to create the drawing without recomputing:
This shows how to travel from vertex 1 to 7 through the shortest path:
