Start from the real weather, air, earthquakes and economy of your city, build a fully-equipped metropolis,
and watch it evolve toward the future — intervene anytime and build it yourself.

🏙 Commercial / residential / industrial zones　🏥 Hospital 🎓 School 🏟 Stadium ⚡ Power 📡 Landmark
🌉 Rivers & bridges　🛣 Elevated ring road　🚄 Railway & trains　✈️ Airport　🍃 Wind & solar　💡 Street lights
📊 Power · Jobs · Health · Education · Traffic — five systems wired into the simulation

▶ Found the City

Needs the internet to load the 3D engine and live data. If location is denied it uses a default city — switch it bottom-left. If the screen is black, open it via a local server (see README).

😕 Engine failed to load

Could not load the 3D engine from the network. Check your connection, or start a local server in this folder:

python3 -m http.server 8000 → open http://localhost:8000/city.html
