This animated scene depicts a night landscape with a moon, house, flower, and butterfly. The moon moves across the screen from right to left, while the butterfly flies between the grass and the sky in a repeating loop. Built with D3.js v5 and SVG, the visualization uses `select`, `append`, and `transition` APIs to create and animate the geometric shapes. The code constructs all elements—rectangles, polygons, circles, paths, and lines—directly, with a black background and dark green grass, demonstrating fundamental DOM manipulation and time-based transitions.
