Sankey charts
=============

Sankey charts are used to visualize the flow of cash in a company.  
The ``plot_sankey_chart`` function will plot a Sankey chart based on data extracted from the Yahoo Finance API.  
Below is an example of how to plot a Sankey chart for ``AAPL`` stock:

.. code-block:: python

   from stockdex import Ticker

   ticker = Ticker(ticker="AAPL")

   ticker.plot_sankey_chart()

The output of the function is a Sankey chart showing the income statement of the company.  
Hovering over the chart will show the amount of cash in each category.  
Below is the output for ``AAPL`` stock based on annual data:
