This example shows a static natural landscape with a sky, sun, mountains, grass, a lake, a tree, and two stick figures, all drawn with SVG shapes. It also layers an animated smiling face on top using D3.js, where the eyebrows move up and down via chained transitions. The visualization pairs declarative SVG markup with D3’s selection and transition API to animate the face, while the surrounding scene remains static. The code uses `d3.select`, `transition.duration`, and `arc()` to construct and animate the facial features. The scene serves as a playful demonstration of combining hand-coded SVG with D3's data-joining and animation capabilities.
