This example visualizes the relationship between engine displacement and horsepower for a collection of automobiles, with each point rendered as a semi-transparent circle and tooltips revealing the car’s name. Built using the Vega-Lite API, the chart is generated programmatically through `vl.markPoint` and `vl.encode` calls, with data loaded via `d3.csv` from a remote CSV file. The visualization is embedded in a web page that imports Vega, Vega-Lite, and Vega-Tooltip, and it automatically fills the browser window with a custom dark theme and large-axis labels.
