This article mainly introduces how to customize the layout scope of the data map in ggplot2, which has a certain reference value, and interested friends can refer to it. I hope you can learn a lot after reading this article.

A small technical problem encountered in the previous contact process is that when ggplot2 makes a data map, when using scale adjustment parameters to limit the range, there are always errors and staggered lines and stripes on the layout.

It should be that there is a conflict between the self-added scaling parameters and the ggplot2 mapping rules, especially the spatial projection parameters, this conflict and confusion become more obvious.

In fact, I just want to get such a data map, instead of cropping the exported picture after making the whole world map. That would look very unfashion.
