BEESWARM

one dot per item packed without overlap along a value axis. Needs: one pooled group of up to ~60 items, each individually meaningful.

DL-01 AGRAW

Use when

every item matters and outliers deserve a name
one pooled distribution where density and gaps are the story

Do not use when

more than ~60 items (CH-DST-01)
several categories compared (CH-DST-03)

See instead

values split across categories: CH-DST-03
too many items to name: CH-DST-01

Alternatives

CH-DST-03 (values split by category)
CH-DST-01 (larger samples)

Rules

deterministic packing: values sorted, first free lane out from the
center; no random jitter, ever
the highlight dot is labeled with name and value; nothing else is
zero-based value axis below the swarm

Never do this

random jitter
labeling every dot
sized dots (use CH-COR-02)
more than ~60 points

QA before delivering

packing deterministic
highlight <= 1 and labeled
zero-based axis
unit once
source present

Data shape

title	action title naming the outlier
source	bottom-left always
unit	on the top axis tick and the highlight label
points	array of {label, value, highlight?}
