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`"]

Out[3]=

Out[4]=

This plots the graph with two different styles, using the layout already calculated:

Out[5]=

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:
