Graph families

In graph theory, "graph families" refer to groups or classes of graphs that share certain properties or characteristics. These families can be defined based on various criteria, including structural properties, combinatorial features, or applications. Understanding graph families helps in categorizing and analyzing graphs, allowing for more efficient algorithms and insights into their behavior. Here are some common types of graph families: 1. **Planar Graphs**: Graphs that can be drawn on a plane without any edges crossing.
