AddEdge(usize, usize, f64)

Insert an undirected edge with the given weight.

RemoveEdge(usize, usize)

Delete an undirected edge.

UpdateEdgeWeight(usize, usize, f64)

Overwrite the weight of an existing (or new) edge.

UpdateNodeAttribute(usize, String, f64)

Set a floating-point attribute on a node.
