[Chicago] Bokeh methods as arguments

[Aaron Elmquist]

Robin,

You might want to look at the getattr so you could writ something like:

    getattr(p, "circle")(x, y, color=color, fill_color="white")

which will pull the circle method off of the p object and pass the
formats.

FYI, I'm not super familiar with bokeh, but I would guess there's probably
a config file that would make setting this up easier.

And looks like Brian beat me to the punch.
