Visualize tree structure and extract feature importances

Using the baseline library model, plot the top 3 levels of the decision tree and extract the feature importances. Create a bar chart of the top 5 most important features and explain if they align with the insights from your earlier data exploration.

Start from the notebook and baseline library model used for the earlier data exploration. Run the existing analysis, then produce a plot of the tree's top three levels and a bar chart for its five highest feature importances. Done means both visualizations are included and the results are explained against the earlier insights.
