GraphNode

A GraphNode is a fundamental component in graph data structures, representing a single entity or vertex within a graph. Each GraphNode typically contains data and references to other nodes it is connected to. In computer science, GraphNodes serve as building blocks for representing relationships between entities in various applications such as social networks, mapping systems, and recommendation engines.

GraphNodes can exist in different types of graphs including directed, undirected, weighted, and unweighted graphs. In a directed graph, connections between nodes have a specific direction, while undirected graphs feature bidirectional connections. Weighted graphs assign values to these connections, representing metrics like distance or cost.

The implementation of a GraphNode varies across programming languages but generally includes properties for storing data and maintaining adjacency lists or edge references. Graph traversal algorithms like Depth-First Search (DFS) and Breadth-First Search (BFS) operate by visiting GraphNodes in specific patterns to explore or process the entire graph.

GraphNodes play a crucial role in representing hierarchical structures, network topologies, and complex relationships in fields ranging from artificial intelligence to database systems. Their flexibility makes them essential for modeling real-world scenarios where entities have interconnections.
