drawio 图形生成器

drawio Graphic Generator

核心工作流

Core Workflow

用户描述 → 解析需求 → 设计图形 → 生成 drawio XML → 验证输出 → 保存文件
详细流程如下：
  1. 接收用户描述
    • 用户可能会描述需要的图类型（流程图、卡片、图表、架构图等）、布局（横向、纵向、网格等）、内容（文字、emoji）和风格（简约、专业、可爱等）。
    • 解析用户输入，提取关键信息以指导后续的图形设计和生成。
  2. 解析用户需求
    • 思考需要绘制的图类型、结构、元素、布局和配色，如果不清楚的情况，请用户确认。
    • 评估元素数量，合理分组，避免单个图形承载过多内容
  3. 根据分析结果，设计图的布局和元素
    • 确定图的整体结构和层次关系
    • 设计每个元素的样式（颜色、形状、大小等）
    • 确定元素之间的连接方式（线条、箭头等）
  4. 生成 drawio 图形代码
    • 使用 drawio 的 mxGraph XML 格式构建图形
    • 应用符合规范的样式（颜色、边框、阴影等）
    • 根据风格选择应用滤镜和阴影效果
  5. 针对生成的图进行验证,通过元素数字计算结果进行验证或者打开drawio程序，利用drawio程序打开图形验证，确保其符合用户需求和预期的视觉效果
    • 基础结构验证（避免元素重叠和布局错乱）：
      • 检查图的结构和元素是否正确
      • 确保所有节点坐标计算准确，无重叠
      • 验证连接线起点/终点精确指向节点边缘
      • 检查文字与图形边界间距充足，避免文字溢出
    • 显示完整性保障（避免显示不完整）：
      • 计算画布尺寸，确保内容完整显示
      • 确保所有节点、文字、连线、箭头都在画布范围内
      • 各边保留足够边距，避免内容被裁剪
    • 箭头与连接验证（避免箭头混乱）：
      • 检查箭头样式统一
      • 验证箭头指向准确，无偏移或错位
      • 检查折线路径节点顺序正确，无交叉混乱
      • 验证虚线仅用于异步流程，错误分支使用实线
    • 样式与颜色验证：
      • 确保颜色和样式符合选择的风格
      • 验证 drawio XML 代码的正确性和兼容性
      • 检查图的布局和元素之间的连接是否合理、线条是否清晰准确、图形是否清晰可读、颜色是否符合预期、排版是否整齐
      • 检查图中箭头是否清晰、连接是否正常、大小是否合适
      • 检查图片是否能够完整显示，是否有元素被截取
  6. 输出最终的 drawio 文件，供用户使用和修改
    • 将 drawio XML 保存到指定路径，文件名以 
      .drawio
      结尾
    • 生成的 drawio 文件可以直接在 drawio 中打开查看和编辑
核心原则：生成的 drawio 图形要简洁美观，符合现代设计规范，与 svg-generator 风格保持一致。
User Description → Parse Requirements → Design Graphics → Generate drawio XML → Validate Output → Save File
The detailed process is as follows:
  1. Receive User Description
    • Users may describe the required graph type (flowchart, card, chart, architecture diagram, etc.), layout (horizontal, vertical, grid, etc.), content (text, emoji) and style (minimalist, professional, cute, etc.).
    • Parse user input and extract key information to guide subsequent graphic design and generation.
  2. Parse User Requirements
    • Determine the graph type, structure, elements, layout and color scheme needed. If unclear, ask the user for confirmation.
    • Evaluate the number of elements, group them reasonably to avoid overloading a single graphic.
  3. Design Graph Layout and Elements Based on Analysis Results
    • Determine the overall structure and hierarchical relationship of the graph
    • Design the style of each element (color, shape, size, etc.)
    • Determine the connection method between elements (lines, arrows, etc.)
  4. Generate drawio Graphic Code
    • Construct graphics using drawio's mxGraph XML format
    • Apply standardized styles (color, border, shadow, etc.)
    • Select and apply filter and shadow effects according to the style
  5. Validate the Generated Graph, verify through element number calculation or open the graphic in drawio program to ensure it meets user requirements and expected visual effects
    • Basic Structure Validation (avoid element overlap and layout disorder):
      • Check if the graph structure and elements are correct
      • Ensure all node coordinates are calculated accurately without overlap
      • Verify that connection line start/end points accurately point to node edges
      • Check that there is sufficient spacing between text and graphic borders to avoid text overflow
    • Display Integrity Guarantee (avoid incomplete display):
      • Calculate canvas size to ensure complete content display
      • Ensure all nodes, text, connections, arrows are within the canvas range
      • Reserve sufficient margins on all sides to avoid content cropping
    • Arrow and Connection Validation (avoid arrow chaos):
      • Check that arrow styles are consistent
      • Verify that arrow pointing is accurate without offset or misalignment
      • Check that the order of polyline path nodes is correct without cross chaos
      • Verify that dashed lines are only used for asynchronous processes, and error branches use solid lines
    • Style and Color Validation:
      • Ensure colors and styles conform to the selected style
      • Verify the correctness and compatibility of drawio XML code
      • Check if the graph layout and element connections are reasonable, lines are clear and accurate, graphics are legible, colors meet expectations, and typesetting is neat
      • Check if arrows in the graph are clear, connections are normal, and sizes are appropriate
      • Check if the image can be displayed completely without elements being truncated
  6. Output the Final drawio File for User Use and Modification
    • Save the drawio XML to the specified path with a filename ending in 
      .drawio
    • The generated drawio file can be directly opened, viewed and edited in drawio
Core Principle: The generated drawio graphics should be concise and beautiful, conform to modern design specifications, and maintain consistency with the svg-generator style.

    <mxGraphModel dx="1200" dy="800" grid="1" gridSize="10" guides="1" tooltips="1" connect="1" arrows="1" fold="1" page="1" pageScale="1" pageWidth="800" pageHeight="600" math="0" shadow="1">
      <root>
        <mxCell id="0" />
        <mxCell id="1" parent="0" />
        
        <!-- Title -->
        <mxCell id="title" value="Graphic Title" style="text;html=1;strokeColor=none;fillColor=none;align=center;verticalAlign=middle;whiteSpace=wrap;rounded=0;fontSize=20;fontStyle=1;fontColor=#333333;" vertex="1" parent="1">
          <mxGeometry x="300" y="20" width="200" height="30" as="geometry" />
        </mxCell>

画布尺寸计算规则

Canvas Size Calculation Rule

画布高度 = 标题高度 + 内容总高度 + 节点间距 × (节点数-1) + 边距
画布宽度 = 边距 + 最大节点宽度 × 列数 + 列间距 × (列数-1) + 边距
Canvas Height = Title Height + Total Content Height + Node Spacing × (Number of Nodes - 1) + Margins
Canvas Width = Margin + Maximum Node Width × Number of Columns + Column Spacing × (Number of Columns - 1) + Margin

节点排列

Node Arrangement

  • 横向流程：节点水平排列，间距 40-60px
  • 纵向流程：节点垂直排列，间距 30-50px

架构图规范

Architecture Diagram Specifications

分层结构

Layered Structure

架构图应采用分层设计，从上到下：
  1. 接入层（客户端、CDN、负载均衡、网关）
  2. 服务层（业务服务、认证服务、消息队列）
  3. 数据层（Redis、MySQL、MongoDB）
  4. 基础层（Docker、K8s、监控）
Architecture diagrams should adopt layered design, from top to bottom:
  1. Access Layer (Client, CDN, Load Balancer, Gateway)
  2. Service Layer (Business Service, Authentication Service, Message Queue)
  3. Data Layer (Redis, MySQL, MongoDB)
  4. Infrastructure Layer (Docker, K8s, Monitoring)

箭头使用规则

Arrow Usage Rules

分层架构图中箭头是可选的：
  1. 无箭头架构图：当重点展示系统层次结构和组件分层时，可以不加箭头。
  2. 带箭头架构图：当需要表示数据流向、调用关系或处理顺序时，可添加箭头。箭头应使用统一灰色（#999999）。
xml
<mxCell id="arrow1" style="edgeStyle=orthogonalEdgeStyle;rounded=0;html=1;strokeColor=#999999;strokeWidth=2;endArrow=classic;endFill=1;" edge="1" parent="1" source="layer1" target="layer2">
  <mxGeometry relative="1" as="geometry" />
</mxCell>
Arrows are optional in layered architecture diagrams:
  1. Arrowless Architecture Diagram: When focusing on displaying system hierarchical structure and component layering, arrows can be omitted.
  2. Architecture Diagram with Arrows: When it is necessary to represent data flow, call relationship or processing order, arrows can be added. Arrows should use uniform gray (#999999).
xml
<mxCell id="arrow1" style="edgeStyle=orthogonalEdgeStyle;rounded=0;html=1;strokeColor=#999999;strokeWidth=2;endArrow=classic;endFill=1;" edge="1" parent="1" source="layer1" target="layer2">
  <mxGeometry relative="1" as="geometry" />
</mxCell>
