Diagramme de Baoyu
/SKILLCréez des diagrammes SVG professionnels au thème sombre, quel que soit leur type : - diagrammes d'architecture, organigrammes, diagrammes de séquence, diagrammes structurels, cartes mentales, frises
name: baoyu-diagram
description: Create professional, dark-themed SVG diagrams of any type — architecture diagrams, flowcharts, sequence diagrams, structural diagrams, mind maps, timelines, illustrative/conceptual diagrams, and more. Use this skill whenever the user asks for any kind of technical or conceptual diagram, visualization of a system, process flow, data flow, component relationship, network topology, decision tree, org chart, state machine, or any visual representation of structure/logic/process. Also trigger when the user says "画个图" "画一个架构图" "diagram" "flowchart" "sequence diagram" "draw me a ..." or uploads content and asks to visualize it. Output is always a standalone .svg file.
version: 1.117.3
Diagram Generator
Create professional SVG diagrams across multiple diagram types. All output is a single self-contained .svg file with embedded styles and fonts.
Supported Diagram Types
| Type | When to Use | Key Characteristics |
|---|---|---|
| Architecture | System components & relationships | Grouped boxes, connection arrows, region boundaries |
| Flowchart | Decision logic, process steps | Diamond decisions, rounded step boxes, directional flow |
| Sequence | Time-ordered interactions between actors | Vertical lifelines, horizontal messages, activation bars |
| Structural | Class diagrams, ER diagrams, org charts | Compartmented boxes, typed relationships (inheritance, composition) |
| Mind Map | Brainstorming, topic exploration | Central node, radiating branches, organic layout |
| Timeline | Chronological events | Horizontal/vertical axis, event markers, period spans |
| Illustrative | Conceptual explanations, comparisons | Free-form layout, icons, annotations, visual metaphors |
| State Machine | State transitions, lifecycle | Rounded state nodes, labeled transitions, start/end markers |
| Data Flow | Data transformation pipelines | Process bubbles, data stores, external entities |
Design System
Color Palette
Semantic colors for component categories:
| Category | Fill (rgba) | Stroke | Use For |
|---|---|---|---|
| Primary | rgba(8, 51, 68, 0.4) | #22d3ee (cyan) | Frontend, user-facing, inputs |
| Secondary | rgba(6, 78, 59, 0.4) | #34d399 (emerald) | Backend, services, processing |
| Tertiary | rgba(76, 29, 149, 0.4) | #a78bfa (violet) | Database, storage, persistence |
| Accent | rgba(120, 53, 15, 0.3) | #fbbf24 (amber) | Cloud, infrastructure, regions |
| Alert | rgba(136, 19, 55, 0.4) | #fb7185 (rose) | Security, errors, warnings |
| Connector | rgba(251, 146, 60, 0.3) | #fb923c (orange) | Buses, queues, middleware |
| Neutral | rgba(30, 41, 59, 0.5) | #94a3b8 (slate) | External, generic, unknown |
| Highlight | rgba(59, 130, 246, 0.3) | #60a5fa (blue) | Active state, focus, current step |
For flowcharts and sequence diagrams, assign colors by role (actor, decision, process) rather than by technology.
Typography
Use embedded SVG @font-face or system monospace fallback:
<style>
@import url('https://fonts.googleapis.com/css2?family=JetBrains+Mono:wght@400;500;600;700&display=swap');
text { font-family: 'JetBrains Mono', 'SF Mono', 'Cascadia Code', monospace; }
</style>Font sizes by role:
- Title: 16px, weight 700
- Component name: 11-12px, weight 600
- Sublabel / description: 9px, weight 400, color
#94a3b8 - Annotation / note: 8px, weight 400
- Tiny label (on arrows): 7-8px
Core Visual Elements
Background: #0f172a (slate-900) with subtle grid:
<defs>
<pattern id="grid" width="40" height="40" patternUnits="userSpaceOnUse">
<path d="M 40 0 L 0 0 0 40" fill="none" stroke="#1e293b" stroke-width="0.5"/>
</pattern>
</defs>
<rect width="100%" height="100%" fill="#0f172a"/>
<rect width="100%" height="100%" fill="url(#grid)"/>Arrowhead marker (standard):
<marker id="arrow" markerWidth="10" markerHeight="7" refX="9" refY="3.5" orient="auto">
<polygon points="0 0, 10 3.5, 0 7" fill="#64748b"/>
</marker>Arrowhead marker (colored) — create per-color as needed:
<marker id="arrow-cyan" markerWidth="10" markerHeight="7" refX="9" refY="3.5" orient="auto">
<polygon points="0 0, 10 3.5, 0 7" fill="#22d3ee"/>
</marker>Open arrowhead (for async/return messages):
<marker id="arrow-open" markerWidth="10" markerHeight="7" refX="9" refY="3.5" orient="auto">
<polyline points="0 0, 10 3.5, 0 7" fill="none" stroke="#64748b" stroke-width="1.5"/>
</marker>SVG Structure & Layering
Draw elements in this order to get correct z-ordering (SVG paints back-to-front):
- Background fill + grid pattern
- Region/group boundaries (dashed outlines)
- Connection arrows and lines
- Opaque masking rects (same position as component boxes,
fill="#0f172a") - Component boxes (semi-transparent fill + stroke)
- Text labels
- Legend (bo
