Minor Changes

  @ganapativs! - Robustness, consistency and legibility pass across all 106 charts.
  Most of this is invisible if your charts already looked right; the parts that aren't are listed under "behaviour
  changes" below.

  Fixed: charts that could hang, crash or vanish. These were all reachable from ordinary props, and each now has a
  regression test.

  • TapeGauge never finished rendering when value was large enough (about 1e16 and up) that its tick step fell below
    one ULP — the tick loop stopped advancing and spun until the tab died. Ticks are now counted, not accumulated, and
    capped.
  • TraceFold hung forever on a parent graph containing a cycle (a span parented to itself, or any two-span loop).
    The critical-path walk now tracks what it has visited.
  • Marks silently disappeared whenever a scale's domain span was infinite — including finite data whose arithmetic
    overflows, such as a Waterfall running total past 1e308. An infinite span yields a slope of exactly 0, which
    passed the old finite check and then produced NaN coordinates. scaleLinear now validates the span itself.
  • PictogramRow's total, Progress's segments, Thermometer's ticks and FoldedDayBand's bins allocated
    one node per unit with no ceiling, so a raw count passed by mistake could exhaust memory. All four now saturate.
  • Charts derived bounds with Math.max(...array), which throws RangeError past roughly 125k elements. Every such
    site now uses a stack-safe fold, so a long series renders instead of crashing.
  • CyclePlot threw on period={NaN} (an empty input field yields exactly that), HeartbeatBlip divided by a zero or
    non-finite window and could put "in the last NaN minutes" into its accessible name, and ActivityGrid accepted an
    unvalidated domain and painted fill-opacity="NaN".

  Fixed: accessibility and inline seating.

  • Labels sitting on a solid mark (HeatCell's upper steps, TimeInRange zones, EventTimeline spans) were rendering
    in body ink instead of on-fill ink — dark-on-dark on the strongest cells. The stylesheet always won over the fill
    attribute these charts were setting, so the intended colour never applied.
  • A decorative interactive chart (summary={false} or live={false}) lost its inline baseline seat, which also
    detached its readout chip and hit box from the mark by up to a seat's height. The live region — which carries the
    seat — now stays mounted and is silenced by emptying it.
  • Visible readout chips and idle labels on MicroDonut, GradeProfile, GardenGrid, QuantileDots and
    EventTimeline composed English inline instead of going through the strings contract, so they stayed English in a
    localized app.

  Behaviour changes worth knowing.

  • Interactive charts now claim only the horizontal touch gesture (touch-action: pan-y pinch-zoom) rather than all
    gestures, so a chart no longer traps the page scroll under a finger; a scroll that takes over now clears the
    highlight.
  • HeatCell and HeatStrip build their step colour by mixing the accent into the band rather than ramping opacity,
    so the steps stay distinct on dark surfaces. The fill moved to the stylesheet, which restores the high-contrast
    (forced-colors) mapping that an inline fill was overriding.
  • DotPlot, Dumbbell and Slope scale their label type and row-name budget with the chart's size instead of using
    a fixed 6-unit font and 6-character cap, so figure-scale charts read properly. Slope steps its type down until the
    labels fit rather than dropping them.

  Added.

  • strings on the static Sparkline, SparkBar and MusicStaff. Their generated accessible name was English-only
    with no override short of writing the whole summary yourself.
  • labelAt on StackedArea, so endpoint share labels can track a scrubbed column.

  Breaking (pre-1.0), types only. SummaryStrings gained quantileDotsChip, quantileDotsOdds and
  timelineFallback. If you supply your own strings object for QuantileDots or EventTimeline, add those three
  templates; every other consumer is unaffected.
