This animated scene depicts a windmill beside a flowing river, with curly white wind paths drifting across a bright sky. The visualization uses D3.js v6 to render and animate SVG elements, including a river whose path oscillates between two bezier curves via chained transitions. Multiple wind curls loop endlessly using `transition.attrTween` to interpolate their horizontal position. The scene demonstrates programmatic landscape drawing with no external data, relying entirely on hardcoded coordinates and animation logic in plain JavaScript.
