This example uses the Vega-Lite API to render a scatterplot of automotive data from a CSV, mapping engine displacement and horsepower onto the x- and y-axes, with color encoding by origin and point size representing miles per gallon. It loads the data via `d3.csv` and builds the visualization with `vl.markPoint`, `vl.x`, `vl.y`, and other encoding functions, then renders to SVG using Vega and Vega-Lite, with a custom tooltip handler and configuration for improved readability.
