This example visualizes automotive performance data by plotting horsepower against country of origin, with vehicle names available as tooltip labels. The code uses the Vega-Lite API to define a circle mark with large size and low opacity, while loading data from a CSV file of auto-mpg statistics using d3.csv. Configuration adjusts axis labels and tick marks for readability, and the visualization renders as a full-window SVG using vega-tooltip for interactive hover details.
