This example presents three side-by-side correlation matrices for male, female, and infant groups, encoded as a grid of colored cells ranging from red to blue. Each matrix uses a diverging color scale, and hovering over a cell highlights its corresponding row and column labels while displaying comparison text below the charts. The visualization is rendered as SVG using D3 v5, with a legend showing the color-to-correlation mapping. Data is loaded from a remote CSV file and processed with `jz.arr.correlationMatrix` to compute correlations.
