This example uses the Vega-Lite API to render an interactive scatter plot of the Auto MPG dataset from the UCI Machine Learning Repository, displaying vehicle weight against horsepower with points colored by origin and sized by weight. A tooltip reveals the car’s name on hover. The code builds the visualization declaratively via `vl.markCircle`, `vl.encode`, and field mappings, then registers Vega-Lite with vega and vega-lite-api, using d3’s `csv` loader for data retrieval and custom configuration for styling axes and labels.
