TuxSparkline

Inline mini trend line. No axes, no legend, no tooltip — the point is "what's the shape of this metric over the last N periods?" alongside a TuxBigStat or TuxFactoid. Native SVG; no chart library.

For first-class native charts with axes / multiple series / confidence bands, see TuxChartLine in design/roadmap.md Priority B.

SR-only summary, auto-derived

The SVG carries a computed aria-label and matching <title> derived from the data: "Trend: 10 points, low 61, high 84, last 84 (+35.5% from first)". Pass units="$M awarded" to append a units suffix; pass aria-summary to override entirely.
