The series carrying the block: the estimate, the curve, the cloud.
The validated block, narrowed to what this adapter can read.
OptionalintervalintervalSeries — the floating column drawing the interval.
OptionalcensoredcensoredSeries — the ticks marking censored times.
OptionalbandbandSeries — the confidence band drawn around a curve.
OptionalpooledpooledSeries — the summary mark at the foot of a forest plot.
Following siblings folded into this layer by merge: further arms of one
survival figure, or further chromosomes of one Manhattan cloud.
One layer an author declared, with everything the chart drew for it.
A figure routinely spreads one layer over several series — an estimate and the column drawing its interval, a curve and the ticks marking its censored times, twenty-two chromosomes that are one cloud — and every one of those extra series is here rather than becoming a layer of its own.
