Why was harry becks tube map so special?

Harry Beck's tube map, designed in 1931, was revolutionary because it used a simplified, non-geographic layout that emphasized clarity and ease of navigation over geographic accuracy. By employing a grid-like structure with straight lines and clear color coding, Beck made it easier for passengers to understand the network and find their way around London’s complex underground system. This innovative approach has influenced transit maps worldwide, setting a standard for public transportation navigation.
