Online service that allows drawing a circle on top of a map?

Question

I need to draw a circle around a central location to show where other places are within a given distance.

As objects, OSM-based Umap only supports Marker, Polyline, and Polygon.

Currently, I take a screenshot, add a circle using Paint Shop Pro, and send the resulting JPG, but I'd rather a live map so people can zoom in/out and move around:

Does someone know of an alternative, preferably with OSM tiles built in, that would also support circle drawing?

Would "Radius Around A Point On A Map" do what you want? You can generate a map URL or download the KML for a given point and radius.

You could use leaflet, an open source JavaScript Library for interactive maps. It supports drawing circles on a webmap using the circle-class. All you need is the geographical point and the radius in meters. You can find a simple example in the quick start guide.

Why not use http://geojson.io/?

You can draw your polygons/circle or use QGIS. Free and open source for geospatial software with a web mapping plugin like QGIS2web.

Then host it anywhere including github pages.

You can just use Google Earth. It provides also a circle measurement tool.
