geom_polygon aes group

[stoneyv]

I attempted to use the geom_polygon method by adapting a ggplot2 geom_polygon example. I omitted the group aesthetic which is not implemented in plotnine. I want to adapt some of my R ggplot2 geo visualization code, but I need to understand plotnine's implementation of geom_polygon first. I can contribute some geo examples to plotnine. Here is a notebook that I saved as a gist.

I pip installed source cloned from master into a conda virtual environment. I am able to successfully produce example visualizations from the notebooks in the plotnine-examples repo. I will try and use the debugger pdb or pudb to step through plotnine this week.

@stoneyv, You do not need to call the draw method, just print the plot or make sure it is the last object in the cell. And, all geoms accept the group aesthetic.

This should work for you

(ggplot(aes('x', 'y' )) +
 geom_polygon(datapoly_df, aes(fill='value', group='iid')))

And, you should have this instead

'iid': np.repeat(ids, 4),

About geo stuff. I am thinking about it. I have an implementation (written a while back) that plots a geopandas dataframe, but I do not quite like it.
