RECHARTS is a term used in the field of cartography, which is the study and practice of making maps. It refers to the process of redrawing existing maps to make them more accurate or up-to-date. This process involves taking an existing map and making changes to it, such as adding new features, correcting errors, or updating information. The resulting map is known as a rechart. Recharts are often used to update existing maps with new data or to create new maps from existing data.
