Diagram Generator

Graphviz-based diagram generation skill using Python.

Features

• ✅ Flowcharts - Business processes, decision trees
• ✅ Architecture Diagrams - System architecture, module relationships
• ✅ State Diagrams - State machines, lifecycles
• ✅ Data Flow Diagrams - Data flow, system interactions

Installation

✅ Already installed:

• Graphviz: System tool (/usr/bin/dot)
• Python graphviz: Library in /tmp/chart-venv/

Usage

Activate Environment

source /tmp/chart-venv/bin/activate

Basic Flowchart

from graphviz import Digraph

# Create flowchart
dot = Digraph()
dot.attr(rankdir='TB')

# Add nodes
dot.node('A', 'Start', shape='ellipse', style='filled', fillcolor='lightblue')
dot.node('B', 'Decision', shape='diamond', style='filled', fillcolor='lightyellow')
dot.node('C', 'Execute', shape='box', style='filled', fillcolor='lightgreen')
dot.node('D', 'End', shape='ellipse', style='filled', fillcolor='lightcoral')

# Add edges
dot.edge('A', 'B')
dot.edge('B', 'C', label='Yes')
dot.edge('B', 'D', label='No')
dot.edge('C', 'D')

# Save as PNG
dot.render('/tmp/flowchart', format='png', cleanup=True)

print("✅ Flowchart generated")

Supported Formats

• PNG: Bitmap format (recommended)
• SVG: Vector format
• PDF: Print format

Node Shapes

• box - Rectangle (normal steps)
• diamond - Diamond (decisions)
• ellipse - Ellipse (start/end)
• circle - Circle (initial state)
• cylinder - Cylinder (database)

Documentation

See GRAPHVIZ-USAGE.md for detailed examples:

• Flowcharts

Quick Test

source /tmp/chart-venv/bin/activate

python3 << 'EOF'
from graphviz import Digraph

dot = Digraph()
dot.node('A', '测试节点')
dot.render('/tmp/test', format='png', cleanup=True)

print("✅ 测试图表已生成")
EOF

ls -lh /tmp/test.png
