I create interactive 3D city visualizations showing how urban areas evolve over time. Using Kepler.gl, building footprint data is visualized in 3D with a time slider based on construction year, revealing the growth of a city. Each building is clickable and includes a direct link to street-level imagery in Google Street View, allowing users to explore the real-world view of the building. This visualization is ideal for urban planning, real estate analysis, city storytelling, and digital twin presentations.
