This visualization shows a correlation matrix for abalone measurements, split by sex (male, female, or infant) via clickable buttons. The upper triangle displays correlation coefficients as colored text, while the lower triangle uses scaled circles, with diagonal labels identifying each variable. The code uses d3.csvParse, d3.scalePoint, d3.scaleSqrt, and d3.scaleLinear, along with the jeezy library’s jz.arr.correlationMatrix to compute correlations. Data is loaded asynchronously via d3.text from a remote CSV, and the SVG is rendered in React with Bootstrap-styled controls.
