In this project we will create an interactive map showing delivery distances based on locations of storage depots. This project is inspired by the problem parcels from Google’s Kick Start coding competition 2019 Round A. The CEO of an important delivery company needs your help to decide where to build new warehouses. You are asked to make an interactive map showing the distances from every warehouse to every square on a 10x10 grid.
