This visualization displays a scatter plot of automotive data, mapping engine displacement on the x-axis against horsepower on the y-axis, with each point representing a vehicle. The plot uses semi-transparent, filled circles to show overlapping data density and includes hover tooltips revealing car model names. It is built using the Vega-Lite API, which wraps the Vega and Vega-Lite libraries, and loads the auto-mpg dataset via D3’s `csv` function. The visualization renders as an SVG, with custom configuration for axis styling and tooltip text.
