Overview

A visual comparison technique that plots real and synthetic bivariate relationships between column pairs to assess correlation fidelity.

Description

Column pair visualization creates plots comparing the joint distribution of two columns between real and synthetic data. Plot types are auto-selected: scatter for numerical pairs, heatmap for categorical pairs, and box for mixed types. This reveals whether the synthesizer captures inter-column relationships.

Usage

Use after generating synthetic data to visually inspect pairwise column relationships.

Theoretical Basis

Bivariate distribution comparison: overlay $P_{r e a l} (X_{i}, X_{j})$ vs $P_{s y n t h e t i c} (X_{i}, X_{j})$ .
