What would you suggest? At the moment it's a bit of a pointless value, but I'm hoping to add a animated function in a later iteration (see how this works in the Zoom module).

Does clearSelection also get called implicitly when you click outside the brush selection? I didn't see this command in the timeseries example.

Yes, this is intended for programmatic use.
When using the built in event handling, if you click, but don't drag we will clear the selection rather than have a zero width selection.

Could we have an example of customizing the view function in this way? Is it possible to, say, have the selected area be a circle? Would the handles, etc. still work?

A circle would be pretty weird, but possible (although it would be very weird for a 2D brush). I could imagine a (slightly) rounded rect for instance, and certainly a different combination of fill/stroke/filter etc attributes.
