In fact, AFAIK, each channel is 22 (some say 20?) MHz wide, while channels are 5MHz apart (except from channel 14).

A better question would be: why not use a square for each channel... Well, supposing that some channels use DSSS the arc is a correct representation. For FHS it would need to be a square (but 802.11 doesn't use FHS) and I'm not sure about OFDM (most probably a square too).

While not much informative, have a look here.
