Connect the ideas
Define vertices and the relationship represented by an edge.
An undirected degree sum equals twice the edge count.
Connectedness concerns routes, not direct links between every pair.
Crossings are not junctions unless marked or specified.
Use weights and constraints when a decision needs more than reachability.
