I have the following data set in python dataframe:

```auto
    sem1|sem2|sem3|sem4
A 2|3|1|3
B 1|2|3|1

```

A and B are in the index column.How do I create a sankey plot for this data to show transition from one semester to another semester

Hi @Sam2, did you take a look at the examples in [https://plot.ly/python/sankey-diagram/](https://plot.ly/python/sankey-diagram/)? Basically you need to extract the values from your dataframe for the `node` and `link` parameter of the trace.

I have passed and plotted the Sankey diagram using the python library.  
But every time when I run, it is generated in local IP with a new port no like [http://127.0.0.1:54245/](http://127.0.0.1:54245/)  
Since I am using real values to plot the Sankey, I want the plot to be used in python so I want my graph to get updated as per the value, so I can use active to show the same graph in python
