This visualization uses the Vega-Lite API to plot automotive data from the auto-mpg.csv dataset, showing car origin along the x-axis, horsepower on the y-axis, and encoding weight through color and mpg through point size. The chart renders as an SVG using vega, vega-lite, and vega-lite-api, with d3.csv loading the data and vega-tooltip providing interactive hover details that reveal each car’s name. A custom config adjusts font sizes and axis colors for readability.
