WebEdge Lists¶ Read and write NetworkX graphs as edge lists. The multi-line adjacency list format is useful for graphs with nodes that can be meaningfully represented as strings. With the edgelist format simple edge data can be stored but node or graph data is not. There is no way of representing isolated nodes unless the node has a self-loop edge.

In other words, a graph G (or g) is defined as a set of vertices (V) and edges (E) that connects vertices. The examples of graph are a social media network, computer network, Google Maps, etc. Each graph consists of edges and vertices (also called nodes). Each vertex and edge have a relation. deuterium has one neutron and one proton
