中文
Diagramon 3.12.0 给图表加了一套"自动配色"：AI 不再随手写色值，而是只标角色；颜色由本地按色系展开，可复现、可一键换、也可以只留在预览里。
下载
| 方式 | 文件 | 说明 |
|---|---|---|
| 安装版（推荐） | Diagramon_3.12.0_x64-setup.exe（约 62.23 MiB） |
装完可用内置自动更新；缺 WebView2 时安装器会自动下载运行时 |
| 便携版（免安装） | Diagramon-3.12.0-win-x64.zip（约 70.33 MB） |
解压到任意位置，双击 diagramon.exe 即用；卸载 = 删文件夹 |
便携版说明：包里是 diagramon.exe + WebView2Loader.dll + ui\ + assets\，必须放在一起
（ui\ 与 assets\ 是从磁盘读的，不在 exe 里）。它不依赖额外要装的东西：不需要 Node.js、
不需要 Chrome、不需要 VC++ 运行库（exe 已静态链接 CRT），只需要 Windows 10/11 自带的 WebView2 运行时。
便携版的「检查更新」照常能发现新版，但更新走的是安装包（不会就地替换便携目录）——
要继续用便携形态，就手动下载新的 ZIP 覆盖。
本次亮点
- AI 只标角色，色值本地落地：模型写"主链路 / 入口 / 判断 / 数据 / 外部 / 异常 / 说明"，应用按色系把角色展开成色值 ——
同一句话两次生成不会出现两套颜色，暗色主题也自动用更亮的一档。跨格式一致：Mermaid / DOT / D2 都能落地。 - 六种色系 + 线框档：松绿 / 黛蓝 / 藕紫 / 橄榄 / 赭石 / 钨灰（无彩，线框与打印）。预览顶栏第三颗按钮切换，
按文件记住；连线一起跟随色系（设置里可关）。 - 打开即挑选：打开没有记过色系的文件时，按图里的角色占比与标签本地选一个（数据/存储多→黛蓝、异常多→赭石、
外部接口多→橄榄、界面词→藕紫，否则松绿），状态栏写明依据。新建文档默认「无」。 - 颜色只留在预览里：换色系、换主题都不改正文；想固化给别人看，菜单里有「写入正文」。
清除（「无」）也只改缓冲区 —— 磁盘要你自己保存。 - 「无」会尽量清干净：先删程序生成的那一段；如果正文里还有手写/外来颜色，且配置了模型，
就让模型只删颜色（结构一改就放弃这次清理）。 - 更安静的资料：连线默认跟随色系但压低饱和度；色系之间按可辨识度重新排过（同一色系内七个角色
填充最小色差从 1.2 提到 3.6–5.9，换色系的差异从 2 提到 17）。
修复
- Mermaid 里带连字符的类名（
A[开始]:::my-class --> B）不再让整份文件解析失败。 - 节点在边上被再次提及时，形状不再被覆盖成方框（判断/圆柱节点之前会被当成主链路）。
- 自动配色失败不再挡住渲染：出图照常，原因写在状态栏。
- 便携版的 README 截图在缺少 ELK 离线包时会显示"加载失败"，已修（截图脚本补上挂载点）。
关于 Diagramon
Diagramon 是一款本地优先的多格式图表编辑器：Mermaid / Graphviz DOT / drawio / Excalidraw
都可编辑并实时预览，AI 可辅助生成、评审与识图。渲染与校验不联网也能用 ——
只有你主动使用 AI 时，相关代码或图片才会发往你选择的上游。
系统要求
- Windows 10 / 11 64 位
- WebView2 运行时（Windows 10/11 通常已预装；缺失时安装器会现场下载）
- 不需要 Node.js、Chrome 或 VC++ 运行库 —— 画布运行时与前端资源都随包分发
安装与更新
下载 Diagramon_3.12.0_x64-setup.exe 直接安装。已装旧版的用户可在
帮助 → 检查更新 里收到本版本（更新包即本安装包，签名见 latest.json）。
本安装包尚未做 Authenticode 代码签名，Windows SmartScreen 可能给出提示。
English
Diagramon 3.12.0 adds automatic colouring: the AI no longer invents hex values, it only tags roles; the app expands them into a palette — reproducible, swappable in one click, and optionally preview-only.
Downloads
| Type | File | Notes |
|---|---|---|
| Installer (recommended) | Diagramon_3.12.0_x64-setup.exe (~62.23 MiB) |
Enables the built-in auto-update; if WebView2 is missing the installer downloads the runtime |
| Portable (no install) | Diagramon-3.12.0-win-x64.zip (~70.33 MB) |
Unzip anywhere and run diagramon.exe; uninstall = delete the folder |
About the portable build: it ships diagramon.exe + WebView2Loader.dll + ui\ + assets\, and those
must stay together (the ui\ and assets\ trees are read from disk, not embedded in the exe).
It needs nothing extra installed: no Node.js, no Chrome, no VC++ redistributable (the CRT is
statically linked) — only the system WebView2 runtime that comes with Windows 10/11.
"Check for updates" still finds new versions, but updating downloads the installer
(it does not replace the portable folder in place) — to stay portable, grab the new ZIP manually.
Highlights
- The AI tags roles, the app picks the colours — the model writes main / entry / decision / data /
external / failure / note, and the palette expands those into values: the same sentence never yields two
different palettes, and dark themes get the brighter ladder automatically. The same tags work in Mermaid,
DOT and D2. - Six schemes plus a wireframe one — Pine / Indigo / Lotus / Olive / Ochre / Tungsten (achromatic, for
wireframes and print). Switch from the third control in the preview toolbar; the choice is remembered per
file, and edges follow the scheme too (switchable in Settings). - Picked on open — a file with no remembered scheme gets one chosen locally from its role mix and labels
(data-heavy → Indigo, failures → Ochre, many external calls → Olive, UI wording → Lotus, otherwise Pine),
with the reason shown in the status bar. New documents start with None. - Colours live in the preview — switching scheme or theme never rewrites the source; 「Bake into source」
is there when you want the colours in the file. Clearing (「None」) only touches the buffer, too — saving
stays your call. - 「None」 tries to leave nothing behind — our own block goes first; if hand-written or foreign colours
remain and a model is configured, the model strips colours only (and the cleanup is discarded if it
changes the structure). - Quieter diagrams — edges follow the scheme at reduced saturation, and the schemes were re-spaced by
measured distance (role fills went from ΔE 1.2 to 3.6–5.9, scheme-to-scheme from 2 to 17).
Fixes
- Mermaid class names containing hyphens (
A[开始]:::my-class --> B) no longer break the whole file. - A node mentioned again on an edge keeps its shape (decision/cylinder nodes were being treated as main path).
- A failed palette expansion no longer blocks rendering: the diagram still draws and the reason lands in the
status bar. - The README screenshots no longer show an ELK "failed to load" message (the capture script now serves the
bundled ELK chunk).
About Diagramon
Diagramon is a local-first multi-format diagram editor: Mermaid, Graphviz DOT, drawio and Excalidraw
can all be edited with live preview, with AI assistance for generation, review and image recognition.
Rendering and validation work with no network at all — code or images reach a model only when you
actively use AI, and then only the endpoint you chose.

Requirements
- Windows 10 / 11 64-bit
- WebView2 runtime (normally pre-installed on Windows 10/11; the installer downloads it if missing)
- No Node.js, Chrome or VC++ redistributable needed — the canvas runtimes and front-end assets all
ship inside the installer
Install and update
Download Diagramon_3.12.0_x64-setup.exe and run it. Users on an older version
will be offered this release via Help → Check for updates (the update package is this same
installer; its signature is in latest.json).
This installer is not yet Authenticode-signed, so Windows SmartScreen may show a warning.
