'Sankey/ Alluvial plots in Python
I am using pandas dataframe in Jupyter notebook and would be interested in generating a Sankey/Alluvial plot. Below is the dataset
import pandas as pd
data = {
'v1_r':[4, 2, 4, 1, 1, 4, 3, 4, 2, 1, 4, 3, 3, 1, 1, 4, 1, 3, 3, 3, 1, 3, 1, 4, 1, 3, 2, 4, 4, 1, 1, 3, 4, 4, 4, 3, 3, 1, 1, 1, 1, 3, 2, 3, 4, 2, 4, 4, 4, 3, 3, 3, 4, 3, 4, 1, 1, 3, 4, 1, 1, 4, 1, 1, 1, 1, 3, 1, 1, 1, 4, 1, 3, 3, 2, 4, 4, 3, 1, 3, 4, 1, 1, 1, 1, 4, 1, 4, 3, 3, 4, 3, 2, 2, 1, 4, 1, 4, 1, 1, 1, 1, 2, 1, 3, 4, 1, 1, 2, 4, 3, 1, 4, 2, 2, 1, 1, 2, 2, 3, 1, 4, 1, 1, 4, 2, 2, 4, 4, 4, 1, 1, 4, 2, 4, 4, 3, 2, 3, 4, 1, 4, 3, 4, 1, 4, 2, 3, 1, 1],
