How to make a mini map for a dungeon RPG?

[TetsuyaHikari]

I've looked through multiple threads about mini maps and such, but they're all for third person RPGs. I have no idea how to go about making a mini map for my own game (or even just a map that can be displayed through a script call). Here is how my interface looks:

It would be nice if the player could push a button to bring up a mini map in the top right corner or access a large map by opening a map (key item). Could someone explain to me how I might go about adding this feature to my project?

Have you tried out Tomy's KMS Minimap? I have seen better minimaps, personally but they require other scripts that I can't find, and this one shows the areas you can walk on and is fairly configurable. It's really cool.
