The main scatter plot maps two numeric attributes from the Auto MPG dataset, encoding vehicle class by color. A smaller, navigator-style scatter matrix repeats four variable pairs across rows and columns, using half-transparent circles to reveal outliers. Built with the vega-lite-api, both views configure axes via shared `config` objects and load CSV data asynchronously through d3.csv. The navigator’s tiny label and title fonts make it a compact overview, while the main chart uses larger text for readability.
