fdg (Force Directed Graph)

A Force Directed Graph Framework for Rust. This manages your forces and event loop for a visualization of a graph. I've also created compatible visualizers for it. This simulation sits on top of petgraph.

Basic Example

```rust use fdg_sim::{ForceGraph, ForceGraphHelper, Simulation, SimulationParameters};

fn main() { // initialize a graph let mut graph: ForceGraph<(), ()> = ForceGraph::default();

// add nodes to it
let one = graph.add_force_node("one", ());
let two = graph.add_force_node("two", ());
let _three = graph.add_force_node("three", ());
graph.add_edge(one, two, ());

// create a simulation from the graph
let mut simulation = Simulation::from_graph(&graph, SimulationParameters::default());

// your event/render loop
for frame in 0..50 {
    // update the nodes positions based on force algorithm
    simulation.update(0.035);

    // render (print) your nodes new locations.
    println!("---- frame {frame} ----");
    for node in simulation.get_graph().node_weights() {
        println!("\"{}\" - {:?}", node.name, node.location);
    }
    println!("-----------------------")
}

} ```
