 GRAPH UTILITIES PACKAGE SYMBOL

GraphCoordinates

 calculates a visually appealing 2D layout of the vertices of the graph g and returns the coordinates of the vertices.
• returns the coordinates of the vertices as computed using a graph drawing algorithm. This is useful when you need to draw a graph repeatedly using the same layout but different styles.
Needs["GraphUtilities`"]
• 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 the LayeredGraphPlot of a directed graph:
only returns the position of the vertices:
The curved edges between vertices 1 and 3 are not reproduced:
This shows how to travel from vertex 1 to 7 through the shortest path:
