A realtime operations dashboard rendering thousands of live data points at 60fps. Charts draw to canvas with a custom diffing layer, so only dirty regions repaint.
Latency from event to pixel sits under 50ms. Operators watch incidents unfold live instead of refreshing, and alert fatigue dropped measurably.
