An undirected graph in discrete mathematical formulation is a structure in which some pairs of objects are in some sense related (Wikipedia). A line with two end points is a graph element with two nodes connected by an edge stretching between the two points.
Here are some examples of graphs:
The above from Wikipedia. Graph with 6 nodes and 7 edges.
This one with 6 nodes and 8 edges.
In Python you can construct a dictionary that associates nodes with edges as shown here in this schematic.
In this graph 5 edges are associated with 6 edges and it can be represented by this dictionary object,

A is connected to B and C while A,B,D and E connects to C.
