This visualization displays the relationship between vehicle horsepower, fuel efficiency (mpg), and weight, with points colored by country of origin and labeled by model name using hover tooltips. It renders an interactive scatter plot from the UCI Auto MPG dataset, loaded via CSV through `d3.csv`. The chart is built using the Vega-Lite API, which composes specifications programmatically, leverages `vl.markCircle` for rendering, and integrates `vega-tooltip` for interactivity within an SVG-based D3 view.
