This visualization uses the Vega-Lite API with D3 to render a scatterplot of automobile data from the auto-mpg CSV dataset. It plots horsepower against origin, with each point sized and colored by its country of origin, and includes tooltips showing vehicle names. The code registers Vega-Lite with Vega and D3, loads data via d3.csv, and configures axes and label styling for improved readability. The plot fills the entire browser window, with rendering handled through Vega’s SVG view and interactivity powered by vega-tooltip.
