How the Map Stuff Works
Set the color for the nation in question.
Go through the Polygon table, finding every polygon for the nation in question.
For each polygon,
Examples
select name, area from nations where code = "fr";
select count(Code2) from borders where Code1 = "us";
select sum(Length) from borders where Code1 = "us";
select name, area, Religions, Percent from nations, Religions where Religions.code
= nations.code;
select nation.Pop, nations.Code, Religions.Religion, nation.Pop*Religions.Percent/100
from Religions, nations where nations.code = "us" and Religions.code
= nations.code;
select Code1, Code2, Length from borders where Code1 = "ch" order by Length
desc; (asc would be the other order)
