A scatter plot displays annual airline passenger counts for five operators—Aeroflot, United Air Lines, Pan American World Airways, American Airlines, and Northwest Orient Airlines—filtered from a remote CSV dataset. Each circle encodes the year on the x-axis, passenger volume on the y-axis, and operator via color. Built with Vega-Lite and rendered through the vega-lite-api, the visualization loads data using d3.csv, applies custom axis styling from config.js, and includes interactive tooltips.
