What is circle grids?

Circle grids are used in various fields such as engineering, architecture, mathematics, and cartography. A circle grid is a set of evenly spaced concentric circles that can be used for various purposes such as measuring distances or creating radial patterns. They are typically printed on a flat surface such as paper or a computer monitor. A circle grid can be used to determine the coordinates of a point on the circular plane using angles and radii. Different types of circle grids include polar coordinate grids, log-polar coordinate grids, and hexagonal grids. Some programs and software applications also offer the option to create and modify circle grids for different purposes.
