Circular Dendrogram

Initial release of the Circular Dendrogram extension for Qlik Sense.

Features:

• Hierarchical visualization as a radial tree with support for 2 to 10 dimensions.
• One measure drives leaf-node sizing via square-root scaling.
• Categorical branch coloring with a Tableau-style palette, plus a single-color mode for minimalist rendering.
• Configurable edge thickness (0.5–4 px) and edge opacity (0.1–1.0).
• Adjustable arc extent: full circle (360°), three-quarter (270°), or semi-circle (180°).
• Configurable start angle (0°–359°) for rotating the entire chart.
• Optional centre circle with configurable radius and color, doubling as an interactive node (hover for chart-wide tooltip, click to clear active selection).
• Optional centre label with Qlik-expression support, configurable size and color.
• Optional per-branch background zones (sectorial wedge tints) that react to selection to reinforce the breadcrumb chain.
• Independent leaf and inner-node label toggles, configurable size (5–32 px) and offset (0–32 px), with a label-density slider (0–100 %) controlling perimeter pruning.
• Four label content modes: dimension name, dimension + value, dimension + percentage of total, or value only.
• Top-N grouping that collapses small branches into a synthetic Others wedge, applied either at the top level only or recursively at each branch.
• Click-to-select with Qlik confirm/cancel toolbar — ancestor chain is brightened with a navy accent on edges, bold larger labels along the path, and a 3-tier wedge tint when background zones are enabled.
• Detailed tooltips for leaves, edges, and the centre node with Qlik-aware number formatting and percentage of total.
• Snapshot and Story support with capture-time license persistence.
• Data export to CSV and Excel.
• Calculation conditions and Include-zero-values via standard Qlik Add-ons.
