I am trying to create a Google My Map of Tokyo Metro and Toei Subway lines. So far, I've been painstakingly drawing the subway lines manually, only using a mouse. Here's what I've got so far (WIP, of course). It is extremely labor intensive to do it this way, and I am convinced there must be a way to automate this process, even if it requires utilizing the Google Maps API or even Google Earth Pro.

Here's another example of the kind of thing I want to do, though obviously not at this scale: https://japonyol.net/editor/ajax.html

Does Google Maps allow you to take a polyline object from the Transit Layer (e.g. the polyline of a subway line) and add the object to a Google My Map?

And if that's not possible, what are some workarounds (some ideas: using the Google Maps API, or Google Earth Pro, or exporting GIS data to KML using ArcMap)?

And if that's not possible, what are some workarounds?

Could it be done using the Google Maps API, or in Google Earth Pro?

Alternatively, would it be easier convert the GIS data into KMLs using something like ArcMap?
