Circular Dendrogram

The Circular Dendrogram extension for Qlik visualizes hierarchical relationships as a radial tree. Branches fan out from the center to leaves on the perimeter, with a line drawn for every parent-child relationship. Each top-level branch is rendered in a distinct color from the active Qlik theme, and node sizes carry your measure — so structure and values read together at a glance.

When to Use It

• Organizational charts — Show divisions, departments, services, and staff in one view.
• Product or service taxonomies — Map a category tree from top-level groups down to individual SKUs.
• Biological or scientific classification — Render kingdom → phylum → class → order → family hierarchies.
• File systems and folder hierarchies — Visualize directory structures with file size as the measure.
• Any nested-category data — Two to ten dimension columns combine into a single readable radial tree.

Key Features

• 2 to 10 dimensions describing the hierarchy levels, plus one measure that drives node sizing, label values, and tooltips.
• Three label layouts — upright Horizontal, rotated Radial, or Outside with lines: labels placed beyond the chart, joined by connector lines that never cross. When space is tight, labels are granted by value — every branch's biggest item is always represented.
• Label density and full-label mode — one slider decides how many labels appear in any layout; an optional toggle renders complete label text without shortening. With name-and-value labels, the value always survives truncation.
• Chart shape and fill — full circle or half circle docked to any side of the tile; Stretch to fill uses the whole tile on non-square cells.
• Node sizing you can tune — nodes size against their siblings or their whole level, with a contrast slider from uniform to maximum spread and an optional cap at the parent's size.
• Colors from your theme — or your expression — branch colors follow the active Qlik theme; node and label colors can be driven by your own color expression, and label text can match its node's color.
• Branch backgrounds — optional color-matched tints behind each branch, extendable behind the outer labels.
• Center hub and images — an optional center circle with its own label, a logo clipped inside the hub, or a faint background image behind the whole chart.
• Top-N grouping — collapse small branches into a synthetic Others node, at the last dimension only or across all dimensions.
• Standard Qlik integration — selections, snapshots, story replay, calculation conditions, and data export.

Why Circular Dendrogram?

• Structure first — unlike a treemap (which packs by value) or a sunburst (which shows totals by ring), a dendrogram draws every parent-child relationship as an explicit line. The shape of the hierarchy is the visual.
• Labels that stay readable — three layouts, density control, and value-ranked label selection keep even crowded charts legible.
• Selection that tells a story — clicking highlights the full path in the theme's selection color, connector lines included; same-value matches elsewhere render dashed; everything unrelated dims. Narrow to a single path and the chart re-renders as a clean centered line.
• Native Qlik experience — theme palettes, calculation conditions, snapshots, and stories work out of the box, and the property panel speaks plain Qlik language with helper notes on the complex controls.
