This visualization presents the top 5 U.S. cities by population in 2023, with each city represented as a white circle that fades in sequentially within a vertically centered panel. The circles are positioned using D3.js transitions, and users can hover over them to trigger a color change from white to a gold-brown, providing interactive feedback. The data is sourced from Wikipedia's list of United States cities by population, and the visualization is rendered as an animated SVG.
