This visualization displays a scatter plot of auto MPG data, showing miles per gallon versus horsepower, with color encoding for origin and size encoding for weight. It uses the Vega-Lite API, rendering through Vega and Vega-Lite libraries with D3 for CSV data loading. The visualization includes tooltips for vehicle names and uses a custom configuration for improved readability. Data comes from the UCI Machine Learning Repository Auto MPG dataset, with a dark theme and larger fonts for enhanced presentation.
