What problem does it solve? Finished WeChat articles often contain complex relationships or data that are hard to follow in plain text. This Skill reviews a final article draft and decides where Mermaid or ECharts diagrams would genuinely improve reader comprehension, returning exact insertion points and ready-to-render chart code. ## Core Features & Use Cases - Chart Placement Planning: Returns up to 3 placements, each anchored to an existing article heading, with purpose, rationale, and fact-source references. - Strict Chart Constraints: Mermaid diagrams are limited to flowchart, sequenceDiagram, and stateDiagram-v2 with at most 8 nodes and 12 edges; ECharts options must be strict JSON using only bar, line, pie, scatter, or radar with numbers verified against the fact base. - Policy-Aware Output: Honors a visualPolicy=off setting (default for opinion pieces) by returning empty placements, and splits oversized diagrams into two readable charts when mobile complexity limits are exceeded. - Use Case: After finishing a hotspot news article in the editor, run the chart suggestion stage to receive JSON placements that the workbench renders as diagrams without altering the article text. ## Quick Start Ask the assistant to analyze the final article draft and suggest Mermaid or ECharts charts with insertion positions and chart code.
