旅程图、饼图与 Git 分支可视化
对于产品设计、高层数据汇报以及技术研发版本管控来说,用户旅程图(User Journey)、饼图(Pie Chart)以及 Git 分支演进图(Git Graph)能起到极佳的可视化辅助效果。
一、用户旅程图:UX 设计核心指南
用户旅程图从用户视角出发,以时间顺序映射用户的行为路径、体验打分与痛点。
journey
title 用户注册与登录产品旅程图
section 探索阶段
浏览官网主页: 5: 访客, 运营专员
点击控制台注册: 4: 访客
section 注册与验证

用户旅程图评分机制与语法解析:
在这段代码中,journey 声明了旅程图。section 划定任务阶段。每一条具体的任务描述,后面跟着冒号 :,接着是评分(1至5分,5分为体验极佳,1分为体验极差),然后是执行该任务的“角色列表”,以及对该任务的核心痛点注解。旅程图非常适合团队内部排查产品痛点、优化操作漏斗流程。
二、Git 图:代码分支管控与可视化
Git 提交网络图(Git Graph)能直观呈现复杂的代码库分支、合并和发布脉络:
gitGraph
commit id: "v1.0"
branch develop
checkout develop
commit id: "feat: auth"
commit id: "feat: docs"
checkout main
merge develop tag: "v1.1"
Git 分支合并、提交与检出核心动作解析:
在 Mermaid 中,Git 提交网络图使用 gitGraph 声明。commit 命令会在当前分支上创建一个新的提交节点。使用 branch develop 会新建一条名为 develop 的研发分支,而 checkout develop 会将当前操作指针指向它,使得之后的 commit 动作全部发生在此分支上。最后,切回 main 主干分支并调用 merge develop 合并,同时打上 tag: "v1.1" 标签。这在讲解团队 Git 工作流(Git Flow / Github Flow)规范、CI/CD 自动化构建逻辑时,具有无与伦比的清晰指导性。
三、饼图:数据占比可视化
饼图主要用于在文档中展示不同指标、浏览器版本、操作系统所占据的市场份额:
pie title 2026 核心编辑器客户端运行占比
"macOS 客户端" : 52.5
"Windows 客户端" : 35.8
"Linux / Web 终端" : 11.7
饼图百分比与应用场景说明:
声明 pie 后跟着 title 属性定义标题。接下来的行采用 "文字" : 数值 的形式。Mermaid 会自动计算所有数值的总和,并智能地在饼图上转化渲染为对应区域大小的弧度和百分比数字。在商业分析、财务开销划分或技术架构汇报中非常易用。
四、常见问题与避坑指南(FAQ)
- 问题:在 Git 图中执行合并
merge时,报错提示分支不存在或者无法合并?- 解决方法:请严格核对您要合并的目标分支名称。合并前必须通过
checkout切换回接收合并的主干分支(如main),再执行merge develop。
- 解决方法:请严格核对您要合并的目标分支名称。合并前必须通过
- 问题:饼图的比例加起来不等于 100%,会导致渲染错误吗?
- 解决方法:不需要手动凑满 100。Mermaid 的饼图引擎是以您的输入数值作为相对比重计算的。例如输入 1, 2, 3,会自动渲染为 16.7%、33.3% 和 50.0%。
Journey, Pie, and Git Graph Diagrams
From UX user experience mappings to numeric distributions and Git branching trees, Mermaid visualizes these elements directly inside Markdown pages.
1. User Journey Diagrams: UX Optimization
User Journey Diagrams plot user tasks, sentiment scores, and user roles sequentially:
journey
title User Registration and Login Journey
section Discovery Phase
Visit official website: 5: Visitor, Marketer
Click registration portal: 4: Visitor
section Verification Phase
Wait for email token: 2: Visitor: Token delay is excessive
Registration succeeded: 5: Visitor
Journey Scoring Metrics and Scope:
The header journey initiates the chart. Sections partition tasks. Each task is defined with a suffix structure: Description: Score: Roles: Friction Notes, where scores range from 1 to 5. This format is great for locating user flow friction points.
2. Git Graphs: Version Control Mapping
Git Graphs trace code checkouts, branching structures, commits, and tags:
gitGraph
commit id: "v1.0"
branch develop
checkout develop
commit id: "feat: auth"
commit id: "feat: docs"
checkout main
merge develop tag: "v1.1"
Git Branching and Checkout Mechanics:
Declared via gitGraph, this diagram is reactive. commit pushes nodes on the current branch. branch name instantiates paths, while checkout switches the workspace pointer. Calling merge back into main with a tag is perfect for training teams on Git Workflows.
3. Pie Charts: Proportional Metrics
Pie charts present quick breakdowns of metrics, configurations, or client shares:
pie title Core Client Platform Metrics 2026
"macOS Clients" : 52.5
"Windows Desktop" : 35.8
"Linux / Web browser" : 11.7
Pie Chart Slicing and Data Format:
Initiated via pie, slice entries are formatted as "Label" : Value. Mermaid parses these values and dynamically computes and overlays percentage tags onto the SVG wedge items.
4. FAQ
- Why does my Git Graph merge action fail to compile?
- Solution: You must checkout the receiving branch (e.g.
main) before callingmerge develop. Also, ensure the merged branch name is defined beforehand.
- Solution: You must checkout the receiving branch (e.g.
- Do my pie chart parameters have to sum to exactly 100?
- Solution: No, the math engine converts all values into absolute percentages automatically based on the cumulative sum of the series.
