What is the best way to create an irregularly shaped tile map in Godot? (fedia.io)

I'm new to Godot and game dev and I've decided to make my first project (having already finished some tutorials) to implement the Diplomacy board game in Godot.

Creating the logic of the game will be the easier part for me as I've been a professional systems programmer (C++/Python) for several years now.

What I'm struggling with right now is how to create the map and the tiles that represent that game board (online example: https://imgur.com/bfnEMup). Since I will want the game to react to a click anywhere in a particular region, I assume I need to have some Area2D that matches the region's shape. The problem is that it's irregularly shaped and I don't know what the best way to accomplish my goal would be.

The options I've thought of so far:

  1. Import the entire map. Then in Godot, create the areas to approximate the regions.
  2. Import the map into some graphics program. Split the map into a sprite for each region. Somehow save the offsets. And import the regions into Godot, each as its own asset. I assume generating a shape from an imported asset is pretty easy.

Any advice or recommendations?

Are you actually asking for how to do this tiles?

If you just want a map with clickable countries, use the full map and add collision with areas and make simple polygon shapes by hand. After that, maybe cut separate country graphics for hover effect.
