Sparse graphs

A sparse graph is a type of network where the number of connections (or edges) between nodes (or vertices) is relatively small compared to the maximum possible connections. In other words, most nodes are not directly connected to many others. Think of a social network where most people have only a few friends, rather than everyone being connected to everyone else. Sparse graphs are common in real-world scenarios like road maps or communication networks because they often efficiently represent systems with limited interactions without clutter. They are useful for analyzing and simplifying complex networks.
