Three side-by-side correlation matrices visualize the relationships among eight physical measurements of abalone, split by sex (male, female, infant). Each cell’s color encodes the Pearson correlation coefficient between two attributes, using a red-blue diverging scale. Computed from the `abalone.csv` dataset, the matrices are rendered as SVG using D3 v6, with d3.mean, d3.sum, and custom functions calculating correlations. Interactive tooltips reveal exact correlation values on hover.
