Charts

27 chart types, one series palette, no charting library.

Marks are the ion and its seven fixed neighbours; series never renumber when one is filtered out. Every plot fills its container and inspects on press or scrub.

<AreaChart stacked> · running-sum bands, overlap by default

<RangeAreaChart> · y hugs the data, never anchored at zero

series pick a mark with line or area · bars by default

<Sparkline values={…} success /> · tone booleans, no hand-built bar rows

<Histogram values={samples}> · bins override the rule

quartiles by interpolation · whiskers at 1.5 IQR · outliers as rings

<ScatterPlot> · numeric x and y, nice ticks on both

steps float by their signed value · a total step snapshots from zero

<PieChart donut> · pressing a slice dims the others

area ∝ value · labels render only where they fit

segments keep chart-1…8 order even when one is zero

each trapezoid narrows to the next stage · conversion from the stage above

<Gauge value={72} label="…" /> · tone booleans recolor the arc

Gauge's sibling · clockwise from 12 · rounded caps

every ring sweeps against one max · press a ring to isolate it

<BulletChart ranges={[…]}> · tone follows the target

rings at nice fractions · values align to axes by index

labels truncate, values never do · track ∝ value

<Heatmap calendar> is the kit's activity calendar · without it, a free cell grid of any density

<UptimeBar> per-period pills · <ServiceHealthList> status by precedence: down › degraded › operational

<GeoMap zoomable> · geometry pre-projected at build time · crowded places merge and split as you zoom
