This example shows a D3.js area chart of normalized highest temperatures across countries, with axis labels and smooth area transitions. The visualization is rendered in SVG within a React framework, using `d3.area` and `scaleBand`/`scaleLinear` scales. Animated clouds drift across a sky gradient, while a recursive tree drawing and a lotus-position Buddha figure appear as decorative elements, created with React components. The chart itself is built with `d3.axisBottom` and `d3.axisLeft`, and animated via React state and `setInterval` for the cloud offsets.
