This scatter plot visualizes the relationship between the origin and horsepower of cars from the Auto MPG dataset. The visualization is built programmatically using the Vega-Lite API, which registers Vega and Vega-Lite libraries to render an interactive SVG chart. It loads data from a CSV file via `d3.csv`, applies custom axis and label styling, and uses a tooltip handler to display car names on hover. The chart automatically fits the browser window dimensions.
