Line chart

Quantitative SSR SVG for latency, queue depth, or any ordered numeric series. Renderer stays Go-native; surrounding panel stays application-owned.

Purpose: Summarize one or more ordered numeric series without browser rendering.
Primitive: line.Line
Kind: components.KindLineChart
Configuration: Label, Caption, axis Labels, named Series, optional Width, and Height.
Accessibility: Figure name comes from Label; Caption stays visible. Keep an adjacent table or text summary when exact values are needed.

Median latency, last seven checks.

Usage Example

@line.Line(line.Config{
  Label: "HTTPS monitor latency in milliseconds",
  Labels: []string{"08:00", "08:01", "08:02"},
  Series: []line.Series{{Name: "Latency (ms)", Values: []float64{42, 47, 51}}},
})

Theme contract

Line and heartbeat resolve Goshtoso semantic CSS tokens at display time. One SSR response follows every built-in theme and its dark mode; no browser chart renderer is involved.
