Here are two common interpretations of "planar cover": 1. **Planar Graph**: If you have a graph that is planar, it means that it can be drawn on a plane without any edges crossing. A planar cover of a graph may refer to a way of embedding or representing the graph in the plane such that it maintains its properties without crossings.
