Deneb Visuals in Power BI (PBIR)

Use pbir for every report mutation. Read PBIR metadata only for diagnosis. If pbir is unavailable or lacks an operation, stop and report the gap; never edit report JSON directly.

Deneb is a certified custom visual for Power BI that enables Vega and Vega-Lite declarative visualization specs directly inside reports. Author specs using this skill.

Provider Policy

Prefer Vega-Lite for new Deneb visuals unless specific Vega-only features are required (signals, event streams, custom projections, force/voronoi layouts). Vega-Lite is more concise, easier to maintain, and covers most chart types. For advanced Vega features, see references/vega-patterns.md and the Vega documentation.

Visual Identity

• visualType: deneb7E15AEF80B9E4D4F8E12924291ECE89A
• Bundled runtime: Vega 6.2.0 / Vega-Lite 6.4.1 (since Deneb 1.8; use v6.json schema URLs)
• Data role: Single dataset role (all fields go into one "Values" well)
• Default row limit: 10,000 rows (override via dataLimit.override)
• Provider: vegaLite (default) or vega (when Vega-specific features needed)
• Render modes: svg (default, sharp text) or canvas (better for large datasets)

Custom Visual Registration (Required)

Copying a working Deneb visual with pbir cp carries its registration. For a new visual, inspect publicCustomVisuals with pbir get and update the complete list through pbir set --json, preserving any existing ids. Never edit report.json directly.
