nebula.js

Build, develop, and review nebula.js (stardust) visualization charts. Use when: creating supernova charts, implementing hooks (usePromise, useLayout, useStaleLayout, useTheme, useRect, useSelections, useInteractionState), setting up the property panel (ext definition, accordion, items), rendering with React inside a supernova component, handling printing/snapshots, avoiding DOM pollution and global CSS. Covers project scaffolding, data binding, selection handling, theme access, resize handling, and debugging patterns. DO NOT USE for mashup/embed API work or Qlik engine configuration.
