Add input parameter to control size of sankey plot

[abhijit-baruah]

The default size does not suit when there are 20+ pathways. Ability to control size as input would be appreciated.

Hey, I know I am late but you can control size like,

sankey(df2["Drug"],df2["Status"], aspect=20, fontsize=10)

fig = plt.gcf()

# Set size in inches
fig.set_size_inches(12, 6)
fig.show()
