Splom

Overview

The splom insight type is used to create scatter plot matrices, which visualize pairwise relationships between multiple variables. It is ideal for exploring correlations, clusters, and patterns in multi-dimensional datasets.

You can customize marker size, color, and lines for each pair of variables in the matrix.

Common Uses

• Pairwise Relationship Analysis: Exploring multiple variable relationships simultaneously.
• Correlation Visualization: Identifying patterns, clusters, or outliers in high-dimensional data.
• Multivariate Data Exploration: Useful in statistics, machine learning, and data science.
