The transformation
This is the code, not a description of it — the chart above was drawn from what it returns, and the notebook download runs the same lines against the same file.
result = df.groupby('region', dropna=False).size().reset_index(name='schools').rename(columns={'region':'group'})
result = result.sort_values('schools', ascending=False).reset_index(drop=True)
if len(result) > 15:
result = pd.concat([result.head(15), pd.DataFrame([{'group':'Other','schools':int(result.iloc[15:]['schools'].sum())}])], ignore_index=True)What it charted
16 rows out of 2,578, 2 columns. First 8 shown.
