CGM curve playground

Stack meals (from a small GI database) and activities on a 4-hour window. The chart shows interstitial glucose in mg/dL as a smooth toy model — useful for intuition, not for dosing or diagnosis.

Disclaimer: This is a simplified educational simulation. Real CGM traces depend on insulin sensitivity, prior meals, sleep, medications, and sensor lag. Do not use this to make medical decisions.
