This example uses the Vega-Lite API to render a scatterplot of automotive data from a CSV file, plotting engine horsepower against the origin of each vehicle. The visualization employs semi-transparent black circles to reveal overlapping points, with tooltips displaying car names on hover. The code registers Vega, Vega-Lite, and Vega-Tooltip libraries, fetches data via d3.csv, and applies a custom configuration for axis styling and label fonts. The chart dynamically fits the browser window using an autosize type of “fit” with padding.
