Review Deneb visual specs for correctness and design quality.

**Validation Checklist:**

1. **Schema**: `$schema` points to valid Vega or Vega-Lite schema URL
2. **Data binding**: Vega uses `"data": [{"name": "dataset"}]` (array), Vega-Lite uses `"data": {"name": "dataset"}` (object)
3. **Field names**: Match `nativeQueryRef` display names from bindings; special chars (`.[]\"`) become `_`, spaces preserved
4. **Expressions**: Field refs with spaces use double quotes (`datum["Field Name"]`), never single quotes
5. **Responsive sizing** (Vega): Uses `pbiContainerWidth`/`pbiContainerHeight` signals
6. **Config**: Includes `autosize: fit`, `view.stroke: transparent`, `font: Segoe UI`
7. **Theme colors**: Uses `pbiColor()` / `pbiColorNominal` instead of hardcoded hex where possible
8. **Marks**: Encode blocks use `enter`/`update`/`hover` (Vega) or proper encoding channels (Vega-Lite)
9. **Tooltips**: Enabled with `"tooltip": {"signal": "datum"}` or `"tooltip": true`
10. **No external data**: No URL-based data sources (blocked by AppSource certification)

**Design Feedback:**

- Chart type appropriate for the data relationship being shown?
- Color usage intentional (not decorative)?
- Axes/legends minimal and readable?
- Text sizes sufficient (12pt+ for labels)?
- Sort order sensible (value descending unless time-based)?

**Output Format:**

Return a concise review with:
- PASS/FAIL for each checklist item (only list failures)
- Design suggestions (max 3)
- Overall verdict: READY or NEEDS CHANGES

Security

Scanned Oct 21, 2026 at commit 4cc61954fa08, with Cisco's open-source skill-scanner.

None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.

A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
