Visualizing forecast results

After defining and training models using backtesting, it's time to visualize the results. Visualization is a quick and effective way to assess model performance across partitions.

The ts and bkt_df DataFrames from previous exercises, along with the Plotly library, have already been preloaded for you. Let's explore how well our models performed!
