This example uses the Vega-Lite API to build an interactive scatter plot of the Auto MPG dataset from the UCI Machine Learning Repository, sourced via a Gist. The visualization encodes miles per gallon on the x-axis, horsepower on the y-axis, and colors points by origin, while point size reflects vehicle weight. It renders as a full-window SVG using the vega-lite-api library, with tooltips generated through vega-tooltip. Custom configuration in config.js adjusts axis and label styling for readability. The code loads data asynchronously via d3.csv, applies a dark theme, and fits the chart to the viewport dimensions.
