This scatter plot visualizes automobile data, mapping engine displacement and horsepower to the x and y axes while encoding weight through circle size and origin through color. The visualization is built using Vega-Lite’s declarative grammar via the `vega-lite-api` wrapper, with `markCircle` and encodings for quantitative and nominal fields. Data is loaded from a CSV file using d3’s `csv` method, and the chart is rendered as an interactive SVG with tooltips provided by `vega-tooltip`.
