Fork of Vega-Lite API Template
This visualization displays a scatterplot of automobile data, plotting engine displacement on the x-axis against horsepower on the y-axis, with tooltips revealing car names. It uses the Vega-Lite API to construct the chart, configured with custom axis styling and a dark color scheme. Data is loaded asynchronously via `d3.csv` from a GitHub-hosted automotive dataset, then rendered through Vega and Vega-Lite, with tooltips provided by the `vega-tooltip` handler. The visualization fills the browser window, applying responsive sizing and opacity to convey point density.
