+## 性能边界
+
+Markdown 可视化会触发多轮 LLM 调用，因此需要明确控制报告生成尾延迟。主流程仍优先从检索后的 `classified_content` 中抽取图表；只有当主流程图表不足、而已生成的子报告正文暴露出新的数据密集候选时，才启动正文补图流程。
+
+正文补图在单个章节内串行执行，不会按候选块并发扇出。当前边界由 `report.py` 中的常量控制：
+
+- 每个章节最多选择 6 个正文候选块。
+- 每个候选块最多生成 3 张互不重复的图表。
+- 每个章节最终最多保留 8 张 Mermaid 图表。
+- 每个章节正文补图最多触发 6 次完整 `_process_visualization_task`。一次完整任务内部可能包含数据抽取、可追溯性校验、合规校验、单位归一化和 Mermaid 生成等多轮 LLM 重试；这个任务预算用于避免数值密集章节在报告正文生成后继续拉长尾延迟。
+
+如果上游报告生成同时处理多个章节，实际同时运行的补图任务数量受上游章节并发策略约束；正文补图自身不会再引入新的候选级并发。

- Invalid if `value_string` is a pure numeric string, `unit_string` is non-empty, or the records are better represented as numeric comparison/composition data.
+## 4. Mermaid Readability Rules
+- Chart labels must be concise enough to render clearly. Mark invalid if category labels or timeline event text are full sentences, raw evidence snippets, or likely to crowd the axis/legend instead of acting as labels.
+- Chart fields must not contain citation markers, markdown links, raw URLs, or source IDs. References belong in surrounding report text or the managed chart caption, not inside Mermaid labels.
+- Common chart words should follow the requested report language implied by `section_outline`; for Chinese outlines, labels like `other` should be localized to `其他` unless it is part of a proper noun.
+- Prefer bar charts over line charts for discrete comparison against separate benchmark years/categories. Use line charts only for continuous/equal-granularity sequences.
+
# Output Constraints
- Output only a valid JSON object with exactly two keys: `valid` (boolean), `error_msg` (string).
- `valid`: true only if relevance and chart type rules are satisfied.

+本文档不覆盖 VLM 图表图片生成，也不覆盖 `#insertChart` 占位符插入。
## 功能目的
-Markdown 可视化用于在报告正文中以 Mermaid 等文本图表形式表达结构化数据。它比 VLM 图表模块更轻量，直接在 Markdown 报告生成阶段工作。
+Markdown 可视化用于在报告正文中以 Mermaid 文本图表表达结构化数据。它比 VLM 图表模块更轻量，直接工作在 Markdown 报告生成链路中。
+
+该能力的边界是：图表数据必须来自检索、筛选和分配到当前章节的 `classified_content` 原始资料，而不是来自模型已经写出的草稿正文。正文生成完成后，系统只负责把已经生成并校验通过的 Mermaid 图表插入到合适位置，不再启动额外的正文后补图抽取流程。
## 可见行为
- 可视化抽取输出必须包含标题、图表类型、records 和单位信息。
-- 支持 bar、line、pie、timeline 等类型。
+- 支持 `bar`、`line`、`pie`、`timeline` 等类型。
- 非 timeline 图表必须有明确且不混合的单位。
-- 单位归一化输出必须通过 schema 校验后才能生成图表。
-- 当主流程已生成的可视化不足以覆盖数据密集内容时，报告生成会从已生成的子报告正文中选择适合可视化的候选块；真正用于 LLM 抽取和溯源校验的 `origin_content` 来自候选块 citation 对应的 `classified_content` 原始资料。
-- 同一章节可以插入多张 Mermaid 图表，但每张图表必须表达一个独立且可追溯的数据集，避免把同一组 records 换一种图型重复表达。
-- 插入到报告正文的 Mermaid 图表会带有系统管理的居中图题；图题引用优先使用图表候选文本中出现的完整 citation 集合，避免跨来源图表只归因到首个来源。
+- 单位归一化输出必须通过 schema 校验后才会继续生成图表。
+- 同一章节可以插入多张 Mermaid 图表；多图来源于章节内多个高数据密度候选资料，而不是正文生成后的二次补图。
+- 插入到报告正文的 Mermaid 图表会带有系统管理的居中图题，并在图题中保留对应 citation。
+- 若某个候选资料抽取、归一化、合规校验或 Mermaid 生成失败，该候选会被跳过；系统不会使用本地正则从正文中硬抽图表数据。
## 性能边界
-Markdown 可视化会触发多轮 LLM 调用，因此需要明确控制报告生成尾延迟。主流程仍优先从检索后的 `classified_content` 中抽取图表；只有当主流程图表不足、而已生成的子报告正文暴露出新的数据密集候选时，才启动正文补图流程。
-
-正文补图在单个章节内串行执行，不会按候选块并发扇出。当前边界由 `report.py` 中的常量控制：
+Markdown 可视化会触发多轮 LLM 调用，因此当前实现只保留正文生成前的主链路：
-- 每个章节最多选择 6 个正文候选块。
-- 每个候选块最多生成 3 张互不重复的图表。
-- 每个章节最终最多保留 8 张 Mermaid 图表。
-- 每个章节正文补图最多触发 6 次完整 `_process_visualization_task`。一次完整任务内部可能包含数据抽取、可追溯性校验、合规校验、单位归一化和 Mermaid 生成等多轮 LLM 重试；这个任务预算用于避免数值密集章节在报告正文生成后继续拉长尾延迟。
+1. 从章节的 `classified_content` 中选择数据密度较高的资料。
+2. 对每个候选资料执行图表数据抽取、校验、单位归一化和 Mermaid 生成。
+3. 子报告正文生成完成后，只执行插入位置规划和 Mermaid 片段渲染。
-如果上游报告生成同时处理多个章节，实际同时运行的补图任务数量受上游章节并发策略约束；正文补图自身不会再引入新的候选级并发。
+系统不在正文写完后再次扫描草稿正文、生成候选、重跑图表抽取或做重复数据去重预算控制。这样可以避免短报告因为补图链路被额外拉长，也能让故障定位集中在主可视化链路本身。

- Input: section_outline: {{section_outline}}, origin_content: {{origin_content}}
- Optional input: desired_chart_type: {{desired_chart_type}}
-- Optional input: avoid_chart_data: {{avoid_chart_data}}
- All extractable data must come only from `origin_content`.
- `section_outline` defines the chapter scope and helps judge relevance.
- If `desired_chart_type` is one of `line`, `bar`, `pie`, or `timeline`, prefer that chart type when it is compatible with the traceable data in `origin_content`. If it is incompatible, choose the best valid chart type instead of fabricating data.
-- If `avoid_chart_data` is not empty, it lists chart datasets that have already been generated for this chapter. Extract a different coherent metric, dimension, or record set. Do not re-express the same records with another chart type. Return `{}` if no distinct valid dataset remains.
- Output language: {{language}}. If output language is Chinese, convert Traditional Chinese characters to Simplified Chinese.
- Keep chart labels readable in Mermaid:
- Do not include citation markers, markdown links, raw URLs, or source IDs in `image_title`, `x_or_category`, or timeline `event_text`.

- 同一章节可以插入多张 Mermaid 图表；多图来源于章节内多个高数据密度候选资料，而不是正文生成后的二次补图。
- 插入到报告正文的 Mermaid 图表会带有系统管理的居中图题，并在图题中保留对应 citation。
- 章节正文写作 Prompt 不允许模型直接输出 Mermaid 代码围栏、图表代码或手写图块；该约束不依赖 `visualization_enable`，因此 VLM 图表开启、Mermaid 可视化关闭时也不会允许正文草稿混入未受控 Mermaid。
+- VLM 图表开启时，如果正文草稿仍意外包含未受控 Mermaid 代码块，VLM 节点会在进入溯源前清理这些代码块；该兜底仅作用于 VLM 链路，不影响本文档描述的受控 Markdown Mermaid 可视化图表。
- 若某个候选资料抽取、归一化、合规校验或 Mermaid 生成失败，该候选会被跳过；系统不会使用本地正则从正文中硬抽图表数据。
+- 在进入多轮 LLM 生图链路前，系统会对候选资料做轻量预算控制：优先尝试数值结构清晰、来源可追溯、数据密度高且与其他候选不重复的资料；简短报告默认减少尝试数，用户明确要求图文并茂或多图时会适度放宽。
+- 当章节只有一张有效 Mermaid 图表时，插入位置规划使用本地规则完成，优先插到匹配 citation 的正文行后；只有多图场景才调用 LLM 规划多张图的相对位置。
## 性能边界
Markdown 可视化会触发多轮 LLM 调用，因此当前实现只保留正文生成前的主链路：
1. 从章节的 `classified_content` 中选择数据密度较高的资料。
-2. 对每个候选资料执行图表数据抽取、校验、单位归一化和 Mermaid 生成。
-3. 子报告正文生成完成后，只执行插入位置规划和 Mermaid 片段渲染。
+2. 对候选资料做轻量排序和预算控制，排序依据是数据密度、原始资料中的数值数量、来源/citation 可追溯性，以及候选之间的重复度。
+3. 对预算内候选资料执行图表数据抽取、校验、单位归一化和 Mermaid 生成。
+4. 子报告正文生成完成后，只执行插入位置规划和 Mermaid 片段渲染；单图场景本地确定插入位置，多图场景再请求 LLM 规划。
-当前实现不在正文写完后再次扫描草稿正文、生成候选、重跑图表抽取或执行重复数据去重预算控制。
