This example shows a scatter plot of automobile displacement against horsepower, with each point sized and colored to reveal density and labeled by car name via tooltips. The visualization is built using the Vega-Lite API (vl) combined with D3’s csv loader to fetch the auto-mpg dataset from a GitHub Gist. The code configures axis styling, a dark color scheme, and an interactive tooltip handler, then renders the chart to fill the browser window using Vega’s SVG renderer.
