IFRS waterfall chart

The script draws multiple waterfall charts, each of which depict sources of changes in balances related to IFRS17. The script is broken down into pieces of code, and explained in a Jupyter notebook, IFRS17 Simulation (Baseline).

The live version of the notebook is available online.
