This example visualizes automotive data from an auto-mpg CSV dataset, plotting engine weight against horsepower with circles colored by origin and sized by miles per gallon. The code constructs the visualization using the Vega-Lite API, registering it with vega and vega-lite, and rendering as SVG via d3.dsv. A custom configuration adjusts axis labels and tick styling for readability, while d3.csv loads the remote dataset. Tooltips display car model names on hover using vega-tooltip.
