数据可视化的判断层 SSOT——画任何图表、dashboard、看板之前先加载它,不是画完之后。管"该不该这么画":这张图想让读者得出什么结论、用均值还是中位数、能不能聚合、堆叠还是折线、能不能上双轴、配色与颜色数量、同一实体跨图是否同色同位、表格该留几列。介质无关:HTML 报告页、React/Vue dashboard、PPT 原生图表、matplotlib/plotly/ECharts/D3、渲染成 PNG 的图,一律适用。Use when 动手画图之前,或评审既有图表("这几张图有什么问题"、"图例为什么不一致")。Not for 报告页的排版/组件/交互(用 report-with-html:report-with-html)或 PPT 原生图表的实现与渲染陷阱(用 deck-creator:deck-creator)。
