Creating a World Map with Features and Random Points

This code defines a function to draw a world map, including coastlines, borders, land, gridlines, and shaded relief. It also randomly marks 10 red points on the map.

Technology Stack : Cartopy, NumPy, Matplotlib

Code Type : Map drawing

Code Difficulty : Intermediate
