Key Concepts

Graph

A graph is a mathematical structure made up of vertices (or nodes) connected by edges. It serves as a fundamental concept in discrete mathematics and computer science, providing the framework to model pairwise relationships between objects.

Tree

A tree is a type of graph that is both connected and acyclic, meaning it has no cycles. Because every pair of vertices is connected by exactly one path, trees have a minimal number of edges, which makes them an efficient structure for various applications like data organization and network design.

Planar Graph

A planar graph is one that can be drawn on a two-dimensional plane without any edges crossing each other except at their endpoints. This property is significant in graph theory and has important implications in areas such as network layout and geographic mapping.

Planar Embedding

Planar embedding is the process of drawing a graph on a plane so that its edges intersect only at their vertices. This concept is crucial when proving the planarity of certain graphs, as it involves demonstrating that a suitable drawing exists where no edges overlap.
