This visualization displays automobile fuel efficiency data, plotting each car’s origin against its horsepower as a scatter plot with semi-transparent circles and tooltips that reveal the vehicle’s name. The chart is built using the Vega-Lite API, which programmatically constructs a Vega-Lite specification that is rendered as SVG through Vega. Data is loaded from a CSV file using d3’s `csv` function. The visualization auto-fits the window and customizes axis and label styling via a config object.
