This example displays a scatter plot of automotive data, with each circle representing a vehicle based on its miles per gallon, horsepower, origin, and weight. The visualization uses the Vega-Lite API within a D3.js context to render interactive SVG graphics. It loads a CSV dataset from a GitHub gist and applies custom encoding for position, color, and size, while tooltips reveal vehicle names. The code integrates vega, vega-lite, vega-lite-api, and vega-tooltip libraries, with the figure automatically fitting the browser window.
