Server Latency Sparkline — Free Sparkline Template
The Server Latency Sparkline template plots API response times across a 24-hour window in a compact, at-a-glance mini chart. The sample data tracks latency every two hours, holding steady around 38-55 ms before a spike to 120 ms at 8h that slowly recovers toward 88-110 ms — a typical pattern when traffic peaks or a slow query hits. It's a ready-made starting point for showing uptime trends or latency health without building a chart from scratch.
