Build distributable Power BI developer visuals: TypeScript/D3 visuals packaged
as a .pbiviz file, written against the powerbi-visuals-api and built with the
pbiviz CLI (powerbi-visuals-tools). This skill covers the full loop: scaffold,
develop, live-preview, package, certify, and publish.
This plugin holds five visual approaches. Choose before building:
deneb-visuals: no-code Vega / Vega-Lite specs inside a report; no packaging, no TypeScript
python-visuals: matplotlib / seaborn script visuals (static image, computes at render)
r-visuals: ggplot2 script visuals (static image); R's stats ecosystem
svg-visuals: SVG drawn by a DAX measure (ImageUrl); inline in tables/cards, no visual sandbox
powerbi-custom-visuals (this skill): a real .pbiviz developer visual, reusable across
reports and shareable on AppSource; full interactivity, formatting pane, certification
Reach for this skill when the need is a reusable, interactive, distributable visual with its own formatting pane. For a one-off chart in a single report, a sibling skill is usually faster and lighter.

patterns are in references/pbiviz-toolchain.md.
This plugin ships a .mcp.json that starts the pbiviz MCP server
(npx -y powerbi-visuals-tools mcp). It grounds development in current, correct API
usage instead of guessed code. Prefer its tools while building:
get_available_apis: look up data, formatting, interaction, and utility APIs with examples
get_best_practices: API-version management, performance, security, accessibility, testing
add_feature: list features available to add (bookmarks, tooltips, drill-down, selection, localization)
implement_feature: step-by-step instructions, code templates, and config changes for a feature
list_visual_info: extract a project's GUID, version, author, data roles, dependencies
check_vulnerabilities: scan dependencies and source for risky patterns (eval, innerHTML)
prepare_certification: verify required files, configuration, capabilities, and assets pre-submission
Setup, client config, and per-tool detail are in references/mcp-server.md.
Certification unlocks export to PowerPoint and email subscriptions, and signals a
reviewed visual. Key gates: a lowercase certification branch matching the package,
eslint-plugin-powerbi-visuals passing, no eval/fetch/XMLHttpRequest, a clean
npm audit, and the latest API. Audit with pbiviz package --certification-audit.
Publishing goes through Partner Center to AppSource. R-based visuals cannot be certified.
Requirements and the submission flow are in references/certification-publishing.md.
Microsoft publishes the full source of official and certified visuals. Start from the
tutorials (circlecard, sampleBarChart) and read a production visual close to the
target (gantt, sankey, sunburst, timeline, ChicletSlicer) for real patterns.
