Graphs

Graphs are visual tools used to represent data and relationships between different items. They consist of points called vertices (or nodes) connected by lines called edges. For example, a graph can show how cities are connected by roads or how different concepts relate to each other. The purpose of a graph is to help us understand patterns, connections, or flows within complex information quickly and clearly. They are widely used in various fields like computer science, transportation, social networks, and more to analyze and communicate data effectively.
