Create a realistic Prometheus/Grafana-style time series chart showing system utilization metrics over a 24-hour period. The chart should include: Two lines: CPU utilization (%) and memory utilization (%) Y-axis bounded from 0 to 100 percent X-axis representing time over the last 24 hours Subtle daily pattern (e.g., lower usage overnight, higher during business hours) CPU showing short spikes and variability Memory showing smoother, gradual changes with occasional step increases Include the following characteristics: CPU fluctuates between 20% and 85%, with brief spikes near saturation (90–95%) Memory gradually increases throughout the day (e.g., from 40% to 75%), with minor drops (e.g., garbage collection or restarts) Near high utilization (above 80%), changes appear more volatile and impactful Visually emphasize: Nonlinear perception near saturation (e.g., highlight the 80–100% range subtly) Occasional periods where CPU spikes but memory remains stable, and vice versa Style: Dark theme (Grafana-like) Clean gridlines Distinct colors for CPU and memory Legend clearly labeling both metrics Goal: The chart should illustrate that utilization is bounded and nonlinear, and that 80% CPU is not simply “twice as bad” as 40%, but closer to a saturation risk zone.
