## 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();
}
```


# 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](https://github.com/grantshandy/fdg/tree/main/fdg-img/examples/web).
