This visualization displays a correlation matrix for the Abalone dataset, split into three separate heatmaps for the male, female, and infant abalone subsets. Each cell shows the correlation coefficient between two attributes, color-coded from red (negative) to blue (positive), with the numeric value overlaid. Hovering over a cell highlights it and displays the specific attribute pair in the text area below. The code uses D3 v5 with SVG rendering, leveraging `d3.scaleLinear` for color mapping and the `jz.arr.correlationMatrix` function from the jeezy library to compute correlations. The data is loaded from the `abalone.data` file.
