chart-story: HyperFrames video primitive (proof and stats / prove)
One chart builds from data in reading order and lands the exact supplied
values. Bars grow staggered from the baseline, a line draws left to right
with an optional translucent area fill, a donut ring sweeps segment by
segment, or horizontal progress bars fill top to bottom. Axis and data
labels fade in reading order; the emphasized datum takes the accent color
and a value callout that pops and settles on the exact value plus unit.
Variables:
- type (bars | line | donut | progress, default "bars"): chart form.
- data (string, default "12, 28, 45, 64"): comma-separated numbers.
- labels (string, default "Q1, Q2, Q3, Q4"): comma-separated labels.
- emphasize (number, default 3): index of the accented datum, clamped.
- unit (string, default "%"): suffix appended to every value.
- accent (green | blue | violet, default "green"): emphasis color.
- exit (none | fade | up, default none): films end on the hold.
Envelope, fixed IN with elastic HOLD only (OUT exists only when exit is
fade or up):
IN_BASE = 3.3s, stage arrival, axis draw, data build, labels, callout
HOLD = max(0, D - IN - OUT), one finite drift then 0.3s stillness
OUT_BASE = 0.5s only when exit is fade or up, otherwise 0
If D is shorter than IN_BASE + OUT_BASE, IN and OUT compress together.
The timeline is never time-scaled.
Determinism: the whole SVG is built synchronously from the variables, all
dash lengths come from getTotalLength (never the pathLength attribute, no
vector-effect on dashed paths), and the callout number rows are authored
frame sets, so repeated or reverse seeks always show the same pixels. The
final displayed values are the raw supplied tokens, never re-rounded.
Mount contract: the runtime clones only this template. #root fills the host
box, establishes the container query basis, has no data-width or data-height,
and registers one paused timeline under the literal chart-story key.
