What are Sankey diagrams how to make them in plotly?

Sankey diagrams these are the diagrams which are the type of flow diagram where the arrows width is comparative to the rate of flow. There are various parameters available which help in visualizing Sankey diagrams that are:

Source - It will represent the source node. Target - It will represent the target node. value - It is used to set the flow volume. label - It will display the name of node.

The representation of quantity is doubled when the flow is twice as wide.

Step 1 - Import library

import plotly.graph_objects as go

Step 2 - Plot the graph

dict(thickness = 8, line = dict(color="yellow", width = 0.3), label = ["First","Second","Third","Fourth","Fifth","Sixth"], color = "green"), link = dict( source = [1,3,4,6,8,9], target = [0,4,6,7,2,3], value = [9,8,4,5,2,1] ))]) fig.show()
