You could try using wb_command -surface-geodesic-rois, it will draw circular ROIs around vertices, as separate maps in a metric file. If you want them all in one map, the -overlap-logic option to that command, and the commands -metric-reduce, -metric-math and -metric-label-import may come in handy.
