Abstract We consider a modified notion of planarity, in which two nations of a map are considered adjacent when they share any $\textit{point}$ of their boundaries (not necessarily an $\textit{edge},$ as planarity requires). Such adjacencies define a map graph. We give an NP characterization for such graphs, derive some consequences regarding sparsity and coloring, and survey some algorithmic results.
