Need to draw a custom world map drawing either the complete world map or a certain region. Also highlighting different regions with different colours.

I have tried https://github.com/KiloKilo/WorldMatrix. I am able to colour the regions but unable to draw custom regions and provide custom colour to certain regions. Unable to find any other library.

Using below code, it shows nothing

let generator = WorldMatrixGenerator()
// Set the number of columns per rows (Default: 100)
generator.columns = 20
// Set your desired map cutting (Default: .world)
// use .custom(north, east, south, west) for a custom bounding
generator.mapCutting = .europe
// Set the output type (.enum, .ascii, .emoji) (Default: .enum)
generator.exportType = .enum
// Generates the world array
generator.generate()

Basically want to achieve the one in the image. Can someone let me know how can draw custom regions?

Thanks for the help in advance.
