This visualization displays car attributes from the UCI Auto MPG dataset, plotting horsepower against origin while encoding weight through both color and point size. It uses the Vega-Lite API alongside vega, vega-lite, d3.csv for data loading, and vega-tooltip for interactive hover details. The chart automatically fits its container dimensions, with custom axis styling and a dark color scheme to enhance readability. Each data point represents a car model, with tooltips revealing the vehicle name.
