Radial Bar Chart | Zyeon UI

status="ready" · Six channels share one 0–1,329 scale (the ceiling is fitted to the largest value, Affiliate, so that ring runs a complete lap). Hovering an arc or tabbing into a legend row lights the same ring and updates the readout; Enter pins it, Esc releases. onSelect is wired — click a row.

Channel volume · last 30 days

Every channel measured against the busiest one, not against itself.

Every category on the shared 0 to 1,329 sessions track (ceiling fitted to this data). Ring 1 is the outermost.
Ring	Category	Value	Share of ceiling	Target	Difference	Note
1	Affiliate	1,329 sessions	100%	1,000 sessions	329 sessions over	on scale
2	Referral	1,121 sessions	84%	1,230 sessions	109 sessions short	on scale
3	Email	925 sessions	70%	970 sessions	45 sessions short	on scale
4	Organic search	476 sessions	36%	490 sessions	14 sessions short	on scale

status="empty" · Valid against the contract but not a single row — kept distinct from "loading" and "the fetch failed".

Every channel measured against the busiest one, not against itself.

Nothing to compare yet

Rings appear here once at least one category has a measured value.

status="loading" · Four concentric skeleton rings plus legend placeholders, aria-hidden, no timer involved; nothing pulses under reduced-motion.

The data source didn't respond.

Degenerate data · One row: a single category still gets a track, a target tick and a scale — it needs no second ring to look deliberate.

Incident closure · this quarter

A single category still gets a track, a target tick and a scale.

Every category on the shared 0 to 40 tickets track (ceiling fitted to this data). Ring 1 is the outermost.
Ring	Category	Value	Share of ceiling	Target	Difference	Note
1	Sev-1 incidents closed	31 tickets	78%	40 tickets	9 tickets short	on scale

Degenerate data · Identical values: the fitted ceiling equals the value itself, so all four rings run full laps — the shape cannot tell them apart, the numbers must, which is why the legend prints every row.

Provisioned quota per region

Identical values under a fitted ceiling: four complete sweeps.

Every category on the shared 0 to 480 vCPU track (ceiling fitted to this data). Ring 1 is the outermost.
Ring	Category	Value	Share of ceiling	Target	Difference	Note
1	eu-west-1	480 vCPU	100%	no target	—	on scale
2	eu-north-1	480 vCPU	100%	no target	—	on scale
3	us-east-1	480 vCPU	100%	no target	—	on scale
4	ap-south-1	480 vCPU	100%	no target	—	on scale

Degenerate data · sweep=360 with the first ring exactly on the fixed ceiling of 100: a single arc command whose endpoints coincide draws nothing at all, so the lap is split into two ≤180° segments to appear.

Pool utilisation (%)

Storage pools against a fixed 100% ceiling, drawn as full laps.

Every category on the shared 0 to 100 track (fixed ceiling). Ring 1 is the outermost.
Ring	Category	Value	Share of ceiling	Target	Difference	Note
1	Hot tier	100	100%	no target	—	on scale
2	Warm tier	62	62%	no target	—	on scale
3	Cold tier	8	8%	no target	—	on scale

Degenerate data · Mixed signs (decimals=1): the floor is pinned to −21.7, so zero sits inside the track and gets a zero ray; negative values sweep back from it with a --card-coloured notch, and Nordics' exact 0 draws no arc at all.

Net revenue change vs last quarter

Zero sits inside the track; anything below it sweeps anticlockwise.

Every category on the shared -21.7 to 18.4 pts track (ceiling fitted to this data). Ring 1 is the outermost.
Ring	Category	Value	Share of ceiling	Target	Difference	Note
1	Americas	18.4 pts	100%	10 pts	8.4 pts over	on scale
2	APAC	3.1 pts	17%	6 pts	2.9 pts short	on scale
3	Nordics	0 pts	0%	2 pts	2 pts short	on scale
4	EMEA	-9.2 pts	-50%	5 pts	14.2 pts short	below zero, drawn anticlockwise
5	LATAM	-21.7 pts	-118%	4 pts	25.7 pts short	below zero, drawn anticlockwise

Degenerate data · Overflow: under a fixed 1,000 ceiling, 1,480 is capped at the end of the track with two notches, and the 1,800 target tick turns dashed and reads off track; the over-long category name truncates to one line, with the full text in title, aria-label and the sr-only table.

Bookings vs the board's 1,000 ceiling

Fixed 1,000 ceiling — values above it are capped, not re-scaled.

Every category on the shared 0 to 1,000 k track (fixed ceiling). Ring 1 is the outermost.
Ring	Category	Value	Share of ceiling	Target	Difference	Note
1	Enterprise renewals — EMEA & UK strategic accounts (incl. public sector)	1,480 k	148%	1,800 k	320 k short	capped at the ceiling; target past the ceiling
2	Mid-market	640 k	64%	700 k	60 k short	on scale
3	Self-serve	0 k	0%	250 k	250 k short	on scale

Degenerate data · Twelve rings (the contract's cap): band width bottoms out at 4 and the gaps are thinner than the rings themselves — all twelve legend rows are still listed, and this is the point to start aggregating the tail.

Requests per service · last hour

Twelve rings is the contract's cap, and it already reads as a smudge.

Every category on the shared 0 to 4,104 rpm track (ceiling fitted to this data). Ring 1 is the outermost.

1	svc-identity	4,104 rpm	100%	no target	—	on scale

Degenerate data · status="ready" with zero rows: the schema refuses this payload, but a caller that skipped the parse still gets the zero-state copy rather than a blank card.

Channel volume · last 30 days

Ready, but the feed came back with no categories at all.

Nothing to compare yet

Rings appear here once at least one category has a measured value.
