Lays out a graph by placing the vertices on a vertical sine wave.
This layout places a graph's vertices on one cycle of a sine wave that spans the rectangle vertically from top to bottom.
If the graph has a metadata key of , only the vertices specified in the value's IVertex array are laid out and all other vertices are completely ignored.
If a vertex has a metadata key of , 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.
