Functions to **convert** NetworkX graphs to and from common data containers like numpy arrays, scipy sparse arrays, and pandas DataFrames. The preferred way of converting data to a NetworkX graph is through the graph constructor. The constructor calls the to_networkx_graph function which attempts to guess the input type and **convert** it automatically. **Adjacency Matrices**: An **Adjacency Matrix** represents a graph as a 2D **matrix** with dimensions V x V where V is the number of vertices of the graph - ωrs: the expected value of the **adjacency matrix** element Aij for vertices i and j lying in groups r and s, respectively - The number of edges between each pair of vertices be independently Poisson.

**Adjacency lists** . An **adjacency list** , also called an edge **list** , is one of the most basic and frequently used representations of a network. Each edge in the network is indicated by listing the pair of nodes that are connected. For example, the **adjacency list** for the Apollo 13 network is as follows: Tom Hanks, Bill Paxton.
