This visualization displays a correlation matrix for the abalone dataset, using color and text to show correlations between numerical attributes like Length, Diameter, and various weight measurements. A color legend with a diverging scale from pink to steel blue accompanies the matrix. The visualization uses D3 v5 and the jeezy library's `arr.correlationMatrix` API to compute correlations, rendering the matrix with SVG elements and adding a dropdown menu to filter data by sex.
