I collected some data of used cars in Germany, which looks like:
Brand | Mode | Price | etc | Zip |
---|
| | | | 64287 | |
| | | | | |
| | | | | |
| | | | | |
I want to create a map which shows the average price and etc of different area/city in Germany.
How can I create a map with zip Code?
Some tips would be nice. Thanks
