Render L-systems as SVGs using Rust and Cairo.
Some useful resources on getting started:

This tool has a command line interface:
Visualize 2D L-Systems with SVGs.
Usage: lsys [OPTIONS] --width <WIDTH> --height <HEIGHT> <AXIOM> <VARIABLES_TO_DRAW> <ANGLE> <ITERATIONS> [RULES]...
Arguments:
<AXIOM> Initial string
<VARIABLES_TO_DRAW> Variables that should be treated as a stroke and drawn
<ANGLE> Turn angle in degrees
<ITERATIONS> Number of times the rules will run
[RULES]... Rules for replacing characters with a new string (i.e. "F=>F+F")
Options:
--width <WIDTH> Width of the SVG Canvas in millimeters
--height <HEIGHT> Height of the SVG Canvas in millimeters
-o, --out <FILE> Path to write the SVG to
-h, --help Print help
-V, --version Print version
To draw four iterations of the Koch snowflake on a 100mm x 100m SVG:
cargo run --release -- --width 100 --height 100 'F++F++F' 'F' 60 4 'F=>F-F++F-F' -o out.svg
Many of the systems below come from Paul Bourke's site.
