A grand, ancient banyan tree at the heart of a dense future city, surrounded by a lightweight, breathable circular wooden structure (Arbor Ring) that displays holographic data about carbon, water, and biodiversity. The tree's canopy merges seamlessly with vertical forests growing on three surrounding skyscrapers, forming a green corridor. Below, a community rain garden and compost center are active. Elderly people collect rainwater, children learn outdoors. The atmosphere is warm, hopeful, and dense with life, showcasing climate-resilient infrastructure. Style: cinematic, detailed, eco-futurism, warm sunlight, photorealistic.
