This visualization displays relationships among automobile characteristics using the Auto MPG dataset from the UCI Machine Learning Repository. Scatter plots show miles per gallon against horsepower, with points colored by country of origin and sized according to vehicle weight. The code builds the chart programmatically using the Vega-Lite API, registering Vega and Vega-Lite with a custom configuration that removes axis domains and adjusts font styling. Data is loaded via D3's CSV reader, and rendering produces an SVG output with a tooltip handler for interactive exploration.
