SVG Logo Generator

Workflow

Before writing any code, follow these steps:

1. Design Analysis

• Analyze the user's request to determine key visual metaphors
• Decide on a color palette using Hex codes
• Plan geometric composition (primitives: circles, rects, paths)

2. SVG Configuration

• Define standard canvas size (e.g., 512x512)
• Always use viewBox for scalability and responsiveness
• Ensure correct XML namespace: xmlns="http://www.w3.org/2000/svg"

3. Python Implementation

• Write self-contained Python scripts
• Constraint: Do NOT rely on external non-standard libraries (like cairo or svgwrite). Use standard string formatting or xml.etree.ElementTree
• Separate styles (CSS within SVG or inline styles) from geometry
• Output/save file as logo.svg

Code Structure

Follow this pattern:

import textwrap

def generate_logo():
    # 1. Configuration
    width, height = 512, 512
    primary_color = "#YOUR_COLOR"
    secondary_color = "#YOUR_COLOR"

    # 2. SVG Header with ViewBox
    svg_header = f'<svg viewBox="0 0 {width} {height}" xmlns="http://www.w3.org/2000/svg">'

    # 3. Geometric Elements
    # Use formatted strings for shapes (Circle, Rect, Path, Polygon)
    shapes = f'<circle cx="{width/2}" cy="{height/2}" r="100" fill="{primary_color}" />'

    # 4. Assembly & Output
    svg_content = f"{svg_header}\n{shapes}\n</svg>"

    with open("logo.svg", "w", encoding="utf-8") as f:
        f.write(svg_content)

    print(f"Logo generated: logo.svg")

if __name__ == "__main__":
    generate_logo()

Key Principles

• Scalability: Always use viewBox instead of fixed width/height alone
• Minimal dependencies: Use Python standard library only
• Separation of concerns: Define styles separately from geometry
• Geometric primitives: Focus on circles, rects, paths, polygons
• Color consistency: Use defined palette with Hex codes
