Circle for Google Maps / Draw a circle on Google Maps.

Right-click anywhere on the map to specify a location, then intuitively display a circle with your chosen radius (e.g., 500m, 2km). By visualizing distances, it's ideal for understanding geographic boundaries—perfect for trade area analysis, area survey strategies, and more.

Due to specification changes in Google Maps, circles may occasionally fail to render. In such cases, we are already working on a fix and waiting for review. Thank you for your patience.
