Writing a Geometric Solver in Python - Part 1: Modelling Constraints
A series covering how to implement a geometric solver in Python. The part 1 looks at how we might represent a set of geometric relationships in a class hierarchy and partially implement this for a `Point`object, and consider the developer experience.

Part 2: More Modelling - In part 2, we take the model from part one and extend it to allow constraints between higher order objects such as `Line` and `Circle`.
