First of all, we have to patch this data, so that it becomes more

useful both for the list and the map. Ox.getCountryByCode gives us
|

the names of the country, region and continent. For the map, we need
|
|
a geoname, and the cities have to be rectangular areas, not just
|
|
points. So we set the area to 100 square meters per inhabitant,
|
|
which will turn out to be relatively realistic. Then we calculate
|
|
how large the resulting square will be, in degrees. (The number of
|
|
degrees from west to east depends on the city's proximity to the
|
|
equator. OxJS has some utility functions built in that make this
|
|
easy to compute.) Finally, we can set the values for south, north,
|
|
west and east. A nice side effect of deriving the size of the city
|
|
from its population is that the map, which will always show the
|
|
largest places in the visible area, will now show the most populated
|
|
cities.
