Planar Graphs. When drawing graphs, we usually try to make them look “nice”. Of course, there's no obvious definition of that. But one thing we probably do want if possible: no edges crossing.

A graph with a loop having vertices labeled by degree. In graph theory, the degree (or valency) of a vertex of a graph is the number of edges that are incident to the vertex; in a multigraph, a loop contributes 2 to a vertex's degree, for the two ends of the edge.
