Graph Toggle by Partition

Input an edge set and a partition line by line using brace notation. The app constructs the complete multipartite graph induced by the partition and toggles its edges. Each graph has its own draggable layout.

Number of vertices Edge set

Write one edge per line using braces, e.g. {1,2}. Leave blank for no edges.

Partition

Write one block per line using braces, e.g. {1,3}. Every vertex must appear exactly once.
