Create a demo using the repo in a Jupyter notebook about openpolicedata HOT 6 CLOSED

Working on building out the example notebook with Denver data. Working on a plot similar to the heat map example @sowdm sent me.

@potto216 If you merge with main, I just removed "Police Department" from all the source names to make it easier i.e.

opd.Source("Denver Police Department") should be changed to opd.Source("Denver")

From this medium article, there is code to make this heat map with the function get_heat_map defined here:
https://github.com/Mjrovai/Python4DS/blob/master/Streets_Santiago/notebooks/10_Streets_of_Santiago.ipynb

def plot_heat_map(data, label, context):
    g = sns.FacetGrid(data=data, 
                      size=6, 
                      dropna=False
                     );

    g.map_dataframe(plot_point_distribution, 
                    shade=True, 
                    alpha=0.7, 
                    cbar=True, 
                    cmap='magma_r', 
                    cbar_kws={'orientation': 'horizontal',
                              'label': label,
                              'fraction': 0.02,
                              'shrink': 0.35,
                              'pad': 0}
                   );

Accidently pushed this to main. @sowdm can you make sure this works for you?

@potto216 I updated a couple small things to make it clearer but otherwise, it looks good.

I got an error on Windows when trying to load in the shape file. Apparently, geopandas uses the fiona package to do this and fiona requires a DLL that didn't install when fiona was installed. I added some instructions for how to get it installed.

Should we close this?

We will see if this is an issue for users
