Remove or update outdated visualisation from examples

[EwoutH]

Currently a lot of our examples still use the old, now removed visualisation. We should either remove, or even better, replace those visualisations with the new SolaraViz visualisation.

All old server.py visualisations should be replaced with app.py files in which SolaraViz is used.

Resources

• Visualisation source code: mesa/visualization/solara_viz.py
• Visualization Tutorial

For reference, these examples currently already use the updated visualisation:

• boid_flockers
• boltzmann_wealth_model_experimental
• hotelling_law
• schelling_experimental
• sugarscape_g1mt
• virus_on_network

We should also start to

• Test examples visualisation in CI #137

With projectmesa/mesa#2214 merged and Mesa 3.0.0a2 released, you can now also specify “shapes” in a portrayal for SolaraViz.

This applies to gis examples too. Need to convert old visualizations to Solara:

• AgentsAndNetworks
• GeoSchelling
• GeoSchellingPoints
• GeoSIR (either remove or copy over from mesa-geo introductory tutorial)
• Population
• Rainfall
• UrbanGrowth

@wang-boyu do you and maybe @tpike3 want to pick that up? Then I will see if I can make the, testable in CI.
