The graph object should be able to have information about weighting of the different area and nodes.

Describe the solution you'd like

A first implementation could implement:

• Uniform weights, to have a base "no weighting" option
• Area weights

These should be modular and extensible classes to enable further implementation of classes that provide more complex and sophisticated weighting options.

Describe alternatives you've considered

Use them directly as edge attributes, but extensibility and making them configurable seems preferable in the long run.
