fdg-img
A simple SVG renderer for fdg-sim
.
Visit the project page for more information.
Basic Example
use std::fs;
use fdg_sim::{ForceGraph, ForceGraphHelper, force};
fn main() {
// initialize a graph
let mut graph: ForceGraph<(), ()> = ForceGraph::default();
// create a circle
let nodes = 10;
graph.add_force_node("0", ());
for x in 1..nodes {
graph.add_force_node(x.to_string(), ());
graph.add_edge(x.into(), (x - 1).into(), ());
}
graph.add_edge(0.into(), (nodes - 1).into(), ());
// generate svg text for your graph
let svg = fdg_img::gen_image(graph, None).unwrap();
// save the svg on disk (or send it to an svg renderer)
fs::write("ring.svg", svg.as_bytes()).unwrap();
}
Webassembly API
This library can be used in Javascript though a WASM interface. I’ll be setting up a demo for it soon. For now you can see how to use it in the web example.
Modules
The style for shapes and text, font, color, etc.
Structs
Parameters for drawing the SVG image.
Functions
Generate an image from a graph and a force.
