I seen a chart like that somewhere but can't remember where. Probably in the electronics board. I can tell you tho that with a 20 cone (the most common) you see an area equivalent to about 1/3rd the depth.

It depends on what degree cone angle and also your depth. With any cone angle, the deeper ,the wider area you see on the bottom.
