SVG Art: Programmatic Generation

Generate high-quality SVG graphics using Python scripts. All scripts output valid SVG to stdout (or file with -o).

Available Scripts

Script	Purpose	Key Options
generate_grid.py	Grid patterns	--cols, --rows, --shape, --vary-*
generate_radial.py	Radial/spiral/sunburst	--spiral, --concentric, --sunburst
generate_fractal.py	Fractals (tree, koch, sierpinski)	--tree, --koch, --sierpinski, --depth
generate_wave.py	Waves and audio viz	--layers, --noise, --bars
generate_particles.py	Scatter/cluster/constellation	--cluster, --gradient, --constellation
generate_chart.py	Data visualization	--bar, --line, --pie, --donut
generate_icon.py	Common UI icons	--icon NAME, --list, --filled
optimize_svg.py	Minify/optimize SVG	--aggressive, --stats

Quick Examples

# Grid with size variation
python scripts/generate_grid.py -c 6 -r 6 --vary-size --vary-opacity -o grid.svg

# Spiral pattern
python scripts/generate_radial.py --spiral -n 60 --turns 4 -o spiral.svg

# Fractal tree
python scripts/generate_fractal.py --tree --depth 8 --vary-angle -o tree.svg

# Layered waves with fill
python scripts/generate_wave.py --layers 5 --fill -o waves.svg

# Constellation network
python scripts/generate_particles.py --constellation -n 30 --connect-distance 25 -o network.svg

# Bar chart
python scripts/generate_chart.py --bar --data "30,50,80,45,90" --labels "A,B,C,D,E" -o chart.svg

# Heart icon
python scripts/generate_icon.py --icon heart --filled --stroke "#E11D48" -o heart.svg

# Optimize existing SVG
python scripts/optimize_svg.py input.svg --aggressive -o output.svg

Script Usage Patterns

Grid Patterns

python scripts/generate_grid.py \
  -c 8 -r 8           # columns and rows
  -s 10 -g 2          # size and gap
  --shape circle      # rect, circle, or diamond
  --vary-size         # random size variation
  --vary-opacity      # random opacity
  --vary-hue          # color variation
  --seed 42           # reproducible randomness

Radial Patterns

# Concentric rings
python scripts/generate_radial.py --concentric --rings 5 --vary-hue

# Sunburst rays
python scripts/generate_radial.py --sunburst -n 24 --vary-length

Fractals

# Koch snowflake
python scripts/generate_fractal.py --koch --depth 4 --fill "#3B82F6"

# Sierpinski triangle
python scripts/generate_fractal.py --sierpinski --depth 5

Charts

# Line chart with points
python scripts/generate_chart.py --line --data "10,30,20,50" --show-points --smooth

# Donut chart
python scripts/generate_chart.py --donut --data "40,30,20,10" --labels "A,B,C,D"

Icons

# List all available icons
python scripts/generate_icon.py --list

# Common icons: check, x, plus, menu, search, home, user, settings,
# mail, heart, star, play, file, download, edit, share, sun, moon, etc.

Common Options (All Scripts)

• --fill COLOR: Fill color (default: #3B82F6)
• --stroke COLOR: Stroke color
• --stroke-width N: Stroke width
• --seed N: Random seed for reproducibility
• -o FILE: Output to file instead of stdout

Piping and Composition

Scripts can be piped together:

# Generate and optimize
python scripts/generate_grid.py -c 10 -r 10 | python scripts/optimize_svg.py --aggressive

# Check optimization stats
python scripts/generate_fractal.py --tree --depth 10 | python scripts/optimize_svg.py --stats
