This scatter plot visualizes the relationship between engine displacement, horsepower, and vehicle origin, with circle size encoding weight. The visualization uses the vega-lite-api to construct the chart, which is rendered with Vega-Lite and Vega. Data is loaded from a remote CSV file of auto-mpg records using d3.csv. The plot maps displacement to the x-axis and horsepower to the y-axis, while color differentiates origin and size scales by weight.
