This is a simple cluster of city distance (time of travel). From the graph you can easily understand which cities to bundle in a trade route, and where to split them in the most efficent way.

These trade routes do not not take profit, or availale goos into account. The are a purely mathimatical analysis of distance. So if you use them as auto traderoutes, the will not yield maximum profit.

You would use them in a scenario where you have a single (or multiple hubs) that provide all your goods and then want to distribute the goods as efficent as possible.
