This scatter plot uses small, solid points to show the relationship between miles per gallon and vehicle weight for cars from the auto-mpg dataset. The visualization is built with the vega-lite-api, which wraps Vega-Lite and Vega to create a declarative chart, then renders it as SVG. Data is loaded via `d3.csv`, and tooltips display the car name on hover. The chart scales both axes from zero and fits the full browser window.
