get positions of graph vertices
(optional) one or more options as specified below
dimension=2 or 3
The number of dimensions in the layout to return. The default is 2.
layout=default, bipartite, circle, fixed, grid, network, planar, random, spectral, spring, tree, or user.
The layout option directs GetVertexPositions to return a previously computed layout with the specified layout method. The name style is a synonym for this option.
If no layout method is specified, the vertex positions corresponding to the default drawing style of the graph are returned.
output=list or Matrix
Specifies whether the points should be output as a list of lists or as a Matrix. The default is list.
The GetVertexPositions('G', 'opts') command returns a list of coordinates representing the positions of the vertices in a previously computed layout.
If a layout is specified with the layout option and this layout was not previously computed, the empty list is returned.
vp ≔ GetVertexPositions⁡CycleGraph⁡9
G ≔ Graph⁡Trail⁡0,1,2,3,4,5,6,7,8,9,1,Trail⁡4,0,7
G≔Graph 1: an undirected graph with 10 vertices and 12 edge(s)
We will disguise the Petersen graph by drawing it using the spring option and make those vertex positions the default.
P ≔ PetersenGraph⁡
P≔Graph 2: an undirected graph with 10 vertices and 15 edge(s)
S ≔ GetVertexPositions⁡P,layout=spring
Q ≔ CopyGraph⁡P
Q≔Graph 3: an undirected graph with 10 vertices and 15 edge(s)
The GraphTheory[GetVertexPositions] command was updated in Maple 2020.
The dimension, layout and output options were introduced in Maple 2020.
