This scatterplot matrix visualizes multivariate outliers across 16 pairwise combinations of four numeric variables from the UCI Auto MPG dataset, with points colored by vehicle class. Built with the vega-lite-api wrapper for Vega-Lite, the small multiples repeat rows and columns via `vl.repeat()`, while d3.csv loads the data. The visualization supports pan and zoom through the panzoom library, with interaction requiring the Alt key.
