Exploratory Analysis: describe the data including the source, the collection method, and variables. Perform exploratory analysis. Also, select few key variables (including the target variable for supervised learning) and study their distributions using plots such as histograms, box plot, bar chart, etc.

The dataset includes both numerical and categorical features. Numerical attributes such as 'duration', 'credit_amount', and 'age' were explored through summary statistics. Categorical features (e.g., 'checking_status', 'employment', 'housing') were encoded for model use. A correlation heatmap was created for numeric features to identify any strong multicollinearity.
