This visualization uses the Vega-Lite API with D3 to render an interactive scatter plot of automobile data from the UCI Machine Learning Repository's Auto MPG dataset. It displays miles per gallon on the x-axis and horsepower on the y-axis, with points colored by origin and sized by weight. The chart encodes tooltips for car names and uses a custom dark-themed configuration from Vega-Lite for improved readability. The visualization is rendered as an SVG that fills the full browser window using D3's CSV loading.
