# Deneb Visuals in Power BI (PBIR) > **Report modification requires tooling.** Two paths exist: > 1. **`pbir` CLI (preferred)** -- use the `pbir` command and the `pbir-cli` skill. Install with `uv tool install pbir-cli` or `pip install pbir-cli`. Check availability with `pbir --version`. > 2. **Direct JSON modification** -- if `pbir` is not available, use the `pbir-format` skill (pbip plugin) for PBIR JSON structure and patterns. Validate every change with `jq empty <file.json>`. > > If neither the `pbir-cli` skill nor the `pbir-format` skill is loaded, ask the user to install the appropriate plugin before proceeding with report modifications. 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](https://vega.github.io/vega/docs/). ## 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 (ov...
