Identifying model drift

Now you'll plot the model scores over time to visualize when drift occurs. By adding the threshold line and RMSE rolling windows, you can see how the trailing error lines indicate performance degradation.

The fc_log dataset with calculated moving averages, rmse_threshold, and Plotly as go have been pre-loaded for you.
