Hello!

I am building a map for a particular province in the world.

How can I draw a border line around a province so that the map markers even look cooler when inside this border on a map?

An example is something like this:

The target province I have in mind does not have the google map bold bordering yet, as shown in the example, but it has the grey broken line border as of the date of this writing, if you know what I mean.

Many thanks
