Three side-by-side correlation matrix heatmaps visualize the Abalone dataset, split by sex (M, F, I), with each cell colored by Pearson correlation strength using a diverging scale. Hovering a cell outlines it in red and displays the compared variables and correlation value in a text panel below. The visualization uses D3 v5 with SVG rendering, the `jz.arr.correlationMatrix` utility from the jeezy library for computations, and a custom color legend derived from a linear scale.
