So the north in the canvas is below, and in real life the north is above.
Because it is based on real coordinates, it is different from the map provided by Guangzhou Metro.
One way of writing the map on the left, another way of writing the map on the right.
On the left, you can select the route from the drop-down menu to view the route, and you can also check which route the station name belongs to; on the right is the full map.
There are no other functions for the time being... Suggestions are welcome.
