[Phys-L] sun path diagram

Hi --

Maybe everybody but me already knows about this, but I
only recently ran across this "sun path diagram".

It's a nifty bit of data visualization.
I like that sort of thing.

This showed up in a gardening discussion group, in the
context of how much direct sunlight a plant will receive
on the north side of a wall.
