How to Create a Sankey Chart
Sankey charts are created using the Sankey.js library, which is open-source and can be easily integrated into any web page. To create a Sankey chart, you will first need to include the Sankey.js library in your HTML code, then create a data array that contains the data that will be displayed in the chart.

Once you have your data array, you can create the Sankey chart by calling the Sankey.visualize() function, passing in the data array and any additional options you wish to use. These options can include things like the maximum flow value, the width and height of the chart, and whether or not to display the data keys on the chart.
