This visualization shows the Sun and the eight planets of our solar system arranged in order, with each celestial body represented by a colored circle that is roughly sized proportionally to its actual size. The sizes use absolute pixel values via CSS, ranging from Mercury at 40px to the Sun at 180px, and the Sun features a radial gradient and glow effect. Saturn includes an elliptical ring element layered behind its circle. The page uses plain HTML and CSS with a flexbox layout for the horizontal arrangement, and JavaScript adds a hover effect that applies a white box-shadow to highlight each selected planet.
