Discover graphs with edge weights.

## Introducing weighted graphs

**Weighted graphs** are a slight generalization of graphs that are useful for modeling more complex problems using graph theory. In an (edge)-weighted graph, each edge is assigned a **weight**, which is usually a number that represents a property of the edge.

For example, consider this undirected graph of subway stations, where each edge represents a train connection. The weight of an edge is a real number representing the distance between the two nodes it connects.
