Function planCities

planCities(
    data: PopulationData,
    sizes?: Record<SettlementSize, SizeClass>,
    network?: Network | null,
): CitySite[]
The settlements to build for a population: one CitySite per settlement, largest first (farmsteads last). Where settlements go and how many people they hold comes from the population model (generatePopulation); this maps them onto size classes. With the population's road network (generateNetworks), each farmstead also gets the nearest road for its driveway. Deterministic from the population.
Parameters
- data: PopulationData
- sizes: Record<SettlementSize, SizeClass> = DEFAULT_SIZE_CLASSES
- network: Network | null = null
Returns CitySite[]
Example
```
const [site] = planCities(generatePopulation(world, { radius: 10_000 }))
const city = await City.create({ world, camera, scene, center: [site.x, site.z], size: site.size, radius: site.radius, seed: site.seed })
```
