This visualization displays a scatter plot of automobile data, mapping vehicle weight to horsepower with points colored by origin and sized by weight. Users can hover over points to see the car model name via tooltips. The visualization is built using the vega-lite-api library, which composes the chart specification through method chaining, while data is loaded asynchronously from a CSV using d3.csv. The chart renders through vega-tooltip and fills the browser window with a custom dark-themed configuration.
