This layout places vertices on a rectangular grid, in two or three dimensions.
Arguments
- graph
The input graph.
- width
The number of vertices in a single row of the grid. If this is zero or negative, then for 2d layouts the width of the grid will be the square root of the number of vertices in the graph, rounded up to the next integer. Similarly, it will be the cube root for 3d layouts.
- height
The number of vertices in a single column of the grid, for three dimensional layouts. If this is zero or negative, then it is determinted automatically.
- dim
Two or three. Whether to make 2d or a 3d layout.
- ...
Passed to
layout_on_grid().
Details
The function places the vertices on a simple rectangular grid, one after the
other. If you want to change the order of the vertices, then see the
permute() function.
