This example builds an animated SVG landscape with a bird, tree, and sun that follows a 24-hour day-night cycle. It constructs SVG elements dynamically using the DOM API’s `createElementNS` and `setAttribute` methods, and creates sky and sun gradients with animated `stop` colors. CSS keyframes (`suntrack`, `moontrack`) rotate the sun and a moon to simulate the sky’s changing illumination, while JavaScript’s `animate` elements update the sky’s hues over a 24-second loop. The scene draws on references to Sara Soueidan’s bird/tree structure and Dudley Storey’s sky design.
