Custom Markers : Numbers inscribed in circles

This is regarding a ANN post-test regression plot (in which the target data are compared with the ANN predictions). The 45 degree (x = y) line plots data versus data; the predictions are usually given solid-circle markers. So, if the predictions are perfect, all the markers will fall on the 45 degree line.
Instead of solid-circle markers, I want clear-circle markers in which are inscribed the serial number of the data point (e.g. 1, 2, 3, etc.)
That way, the reader can quickly see which data points are being predicted perfectly and which are not.

You'll have to use the rectangle() function to make the circles, and then use text() to create the number labels that go inside the circles.
