Plot on Google Maps using the python library (bokeh)

There are two problems.

Please reference the attached the ppt file.

First, I want to plot some data on Google Maps using the python library (bokeh).
I tried several times.
I can plot 'circle ', however, I can't plot 'quad'.
Can you plot using 'quad' method?

Second, I want to show 'x_axis_label' on Google Maps.

I uploaded one code and sample data.
