Data Exploration
Clinical Feature Analysis
Investigating feature distributions and multivariate relationships within the clinical data.
Provenance: Cleveland Clinic Foundation (Processed)
The bundled clinical benchmark dataset for this project. It contains the cleaned Cleveland cases used for training, evaluation, and exploratory analysis.

Distribution of every field
Clinical Distribution Benchmark
Each chart visualizes a single clinical metric across the patient population. Numeric fields use shared bins with side-by-side bars, while coded fields use grouped bars. Bar height represents the number of patients in each value or range, colored by diagnosis: No Disease (Green) vs Heart Disease (Crimson).
Summary statistics (Average and Median) are provided below each chart to describe the central tendency of the data for each attribute.
