 ### 3. Visual & Diagram Sync
 *   **Mermaid Charts:** 
     - Update the "Major Ecosystem Pillars" pie chart to align with the **Strategic Dimensions** defined in the V2 portal.
-    - **Annual Growth Distribution**: Include two Mermaid pie charts: one visualizing the historical distribution of commits by year, and another visualizing the estimated knowledge growth (New Refs) by year, perfectly synchronized with the Annual Growth Summary table.
+    - **Annual Growth Metrics**: Include a Mermaid `xychart-beta` bar chart comparing "Commits" and "Estimated New Refs" side-by-side for each year, perfectly synchronized with the Annual Growth Summary table.
 *   **Linguistic Diversity**: Maintain a dedicated chart visualizing the project's commitment to **Global Access** (Mandate 10).
 *   **Architecture Flow:** If the Agentic Stack or the deployment lifecycle changes, the corresponding Mermaid diagrams MUST be updated immediately.
 *   **Robustness:** Follow the "Mermaid Diagram Best Practices" (node quoting, explicit direction) as defined in this document.
