This interactive scatter plot visualizes the relationship between miles per gallon, horsepower, weight, and origin for a set of automobiles loaded asynchronously from a CSV via D3’s `csv` function. Rendered with the Vega-Lite API, the chart encodes continuous fields on x- and y-axes, categorical origin on color, and weight on point size, with tooltips revealing car names. The visualization adapts to the window size and uses a custom dark theme defined in a shared config object, with D3 version 5 and Vega-Lite v4.0.0-beta.1.
