This visualization displays a scatter plot of automobile data from the UCI Machine Learning Repository’s Auto MPG dataset, with engine horsepower on the y-axis and miles per gallon on the x-axis. Points vary in color by country of origin and size by vehicle weight, with tooltips revealing car names. The code uses the `vega-lite-api` to build the chart, which registers with Vega and Vega-Lite, while D3’s `csv` loads the data. A custom `config` object adjusts axis and label styling for readability.
