This example demonstrates a scatter plot of automobile data, showing the relationship between miles per gallon, horsepower, weight, and country of origin. It uses the Vega-Lite API to build the visualization declaratively, with the `vl.markCircle` and `vl.encode` methods specifying the visual encodings. The data is loaded from a CSV file via `d3.csv`, and the plot is rendered to an SVG canvas using the Vega rendering engine. The template also configures chart styling through a custom `config` object and enables interactive tooltips with the Vega Tooltip handler.
