status="ready" · 24 stores, 23 joins, and the four demand profiles the analysis found. The payload carries the cut it chose (0.45) and the chart starts there: every branch that closed below it is one cluster, drawn in its own colour with its letter on the rule and beside every one of its tip labels. Drag the slider down and the colours split; drag it up and they merge. The wide empty band below 0.52 is the finding — nothing joins anywhere in it, which is why a cut placed anywhere inside it gives the same four clusters.

Stores by weekly demand profile — the clusters at a cut of 0.45. A cluster is a branch whose every join happened at or below the cut; “forms at” is the height of its own top join and “joins the rest” is the height at which it merges with anything else. stores are listed in the order the chart draws them, and every join is reachable by tabbing into the tree.

status="empty" · a valid contract with no linkage in it, told apart from loading and from a failed fetch.

Stores by weekly demand profile

Where two things joined, and how far apart they still were when they did

No clustering to draw

A dendrogram needs the linkage itself — every join and the height it happened at. A table of items with a cluster label already threw that away, and no tree can be rebuilt from it.

status="loading" · eight skeleton brackets, aria-hidden, honouring prefers-reduced-motion, with no timer involved.

status="error" · the fetch failed. Try again only appears when onRetry is passed, and clicking it flips the card to ready.

Awkward linkage · every way a linkage can arrive broken, in one payload. Two kiosks with identical profiles join at height 0 (a bracket with no width, not a dropped row). Harbourfront closes at 0.22 and its parent at 0.14 — an inversion, which centroid linkage really does produce, drawn as it came. Five joins cannot be drawn at all: one has a NaN height, one names a missing id, one tries to take a node that was already joined, and two name each other in a loop. Their sites are all still on the card as separate roots, the notes say exactly what was refused, and the last label is far too long for the gutter so it elides with the whole string on its tooltip.

Awkward linkage

10 sites · 4 joins · heights 0 to 0.31 · cut at 0.2 → 7 clusters

Cut height0.2 · 7 clusters

cluster marker, on the cut
folded branch
distance grows to the left · 1 − Spearman ρ · centroid linkage

5 joins could not be drawn: 1 carried no usable height and 4 named a child nothing could supply — a missing id, a node already joined, or a loop. Their sites are all still here as separate roots: a dropped join never takes anything with it.

This payload never joins everything into one tree — 6 separate roots are stacked here, and no height was invented to link them.

1 join sits lower than a join inside it — an inversion, which centroid and median linkage produce honestly. It is drawn as it came, so the crossing you see is in the data and not in the layout.

Awkward linkage — the clusters at a cut of 0.2. A cluster is a branch whose every join happened at or below the cut; “forms at” is the height of its own top join and “joins the rest” is the height at which it merges with anything else. sites are listed in the order the chart draws them, and every join is reachable by tabbing into the tree.

maxLeaves={14} on 183 products · far more tips than a card has rows, so the deepest branches fold into wedges labelled with what they hold, keeping the top of the tree where the structure is. Nothing is unreachable: click a wedge, or press Enter on it, and it opens — one budget's worth of rows at a time, so a single keystroke can never turn 183 items into 183 rows. Every height on the card is still computed from all 183.

No cut in the payload, showCutControl={false} · a static figure for a report. With nothing supplied the chart cuts at the widest gap between merge heights — the oldest way of reading a dendrogram — and says “(widest gap)” in the summary so the number is never mistaken for a decision someone made. The tree stays fully keyboard-navigable without the slider.

order="input" · the same tree, the same heights and the same four groups of stores — only the vertical order has changed, because a linkage fixes the tree just up to swapping the two sides of every join. The letters follow the picture, so what was A above may be C here. Payload order is the honest choice when the tips already carry an order of their own; the default puts the smaller, tighter branch on top, which is what makes the classic ladder readable.
