$ pip install viscm[PySide]
...or:

There is some information available about how to interpret the resulting visualizations and use the editor tool on this website.
Load viridis AKA option_d.py using:
viscm --uniform-space buggy-CAM02-UCS -m Bezier edit /tmp/option_d.py
Note that there was a small bug in the assumed sRGB viewing conditions
while designing viridis. It does not affect the outcome by much. Also
see viscm --help.
