What type of map projection is used for data representation?

For data representation, the choice of map projection often depends on the specific purpose of the data being conveyed. Commonly used projections include the Mercator projection for navigation due to its angle preservation, the Robinson projection for a visually appealing world map, and the Lambert Conformal Conic projection for aeronautical charts. Each projection has its strengths and weaknesses, affecting area, shape, distance, or direction, which should be considered based on the data's requirements.
