autodesk-platform-services/aps-iot-extensions-demo — reverse-engineered prompt

Build me a small web demo that shows IoT sensor data inside an Autodesk building model. I want to open a 3D model in the browser, see rooms and sensor points tied to locations in the model, and have the values update from mocked sample data so it feels live. It should use the Autodesk Platform Services Data Visualization tools to show things like heatmaps or room level readings when possible.

Please make it easy to run locally with my APS client ID and secret, and make it clear where I should paste my model URN and view ID. Use the sample sensor setup as a starting point, but structure it so I can tweak sensor positions, room links, and the random value ranges without much effort. A simple Node based app is fine, and it should start on localhost and work as a demo without needing a real IoT backend. If anything about the viewer setup has changed, look up the current APS docs online and wire it up correctly.
