This visualization displays automobile data from a CSV file, plotting engine displacement on the x-axis against horsepower on the y-axis as semi-transparent points. The Vega-Lite API configures the mark, encoding, and tooltips, with custom axis styling from the configuration file. Data is loaded asynchronously using d3.csv from a GitHub gist, and the resulting chart is rendered with Vega’s SVG renderer. The visualization fills the browser window, with tooltips enabled via Vega Tooltip.
