WebUtility graph K3,3. In graph theory, a planar graph is a graph that can be embedded in the plane, i.e., it can be drawn on the plane in such a way that its edges intersect only at their endpoints. In other words, it can be drawn in such a way that no edges cross each other. [1] [2] Such a drawing is called a plane graph or planar embedding of ... WebEdge lists. One simple way to represent a graph is just a list, or array, of E ∣E ∣ edges, which we call an edge list.

WebAug 30, 2015 · Yes, a disconnected graph can have an Euler circuit. That's because an Euler circuit is only required to traverse every edge of the graph, it's not required to visit every vertex; so isolated vertices are not a problem.
