And get out a polygon (probably default to GeoJSON) approximating the circle of that radius at that point.
Optionally we could take an argument to specify the number of points used for the circle-ish polygon, but I think for starters it's fine to just pick a number.
Eventually it would be cool to support a general-purpose buffer command for all geometries, but the implementation of that is somewhat complex (JTS version is here for reference) and it doesn't look like there is an existing rust implementation of it yet. So starting with just points seems fine and still useful.
