 We can perform exactly the same fix for diverging, circular, miscellaneous and qualitative color maps. Let's take a diverging color map as an illustrative example:
 
 ```python
-# fixing the color map, using the same minimal lightness (lift=None), 
-# not normalizing to bitone and 
-# smoothing the chroma
-sc_map.unif_sym_cmap(lift=None, 
-                     bitonic=False,
