fdg-img

A simple SVG renderer for fdg-sim.

Basic Example

```rust 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();

} ```
