This example displays a scatter plot matrix of 36 pairwise combinations from 12 selected columns of the Cardiology dataset, with each point colored by its outlier status. Built with the Vega-Lite API and rendered using d3.v7, it uses repeated row and column encodings with `vl.markCircle`. A brush parameter allows users to select points via Ctrl-click, while the panzoom library enables zooming and panning on the entire chart.
