C# Class Smrf.NodeXL.Layouts.GridLayout

Lays out a graph by placing the vertices on a grid.

This layout places a graph's vertices on a simple grid.

If the graph has a metadata key of , only the vertices specified in the value's IVertex collection are laid out and all other vertices are completely ignored.

If a vertex has a metadata key of with a value of true, it is included in layout calculations but its own location is left unmodified.

If you want the vertices to be placed in a certain order, set the property to an object that will sort them.
