This example visualizes the relationship between engine displacement and horsepower for individual car models, using a scatterplot where each point represents a vehicle and hovering reveals its name via tooltips. Built with the Vega-Lite API, it streams data from a CSV file loaded through D3’s `csv` method, renders an SVG chart via Vega’s renderer, and applies a custom dark-themed configuration for axes and labels. The visualization fills the entire window and uses adaptive sizing, with data preprocessing and API registration handled in `index.js`.
