This visualization presents a scatter plot of auto MPG data from the UCI Machine Learning Repository, mapping miles per gallon against horsepower. Each circle’s size encodes vehicle weight, while color distinguishes origin, and hovering reveals the car’s name. The visualization is built using the Vega-Lite API, with d3.csv loading the data and vega-tooltip providing interactive details. The chart fills the browser window, and a custom config adjusts axis and label styling for readability.
