Horizontal bar chart showing latency distribution across 5 buckets: 0-50ms, 50-100ms, 100-200ms, 200-500ms, 500ms+. Color-coded green (fast), yellow (medium), red (slow). Shows count per bucket. Appears in the full-screen detail panel (Enter) after the sparkline stats. Skipped for push monitors (no latency data).
