Chapter 51: Spokes

You are given a grid of hubs, some of which are numbered. Draw horizontal, vertical, or diagonal connections between hubs while following these rules:

A line may only start from a visible hub point.
At most one line may connect the same pair of hubs.
A hub’s number tells you how many lines start from it.
Lines may not cross.
All hubs must end up in a single connected network.

Spokes is documented here from x-sheep/puzzles-unreleased. The original inventor is unknown.
