Struct FrParams 

pub struct FrParams {
    pub niter: u32,
    pub start_temp: Option<f64>,
    pub grid: FrGrid,
    pub weights: Option<Vec<f64>>,
    pub bounds: FrBounds,
    pub seed_coords: Option<Vec<(f64, f64)>>,
    pub rng_seed: u64,
}

Parameters for the 2D Fruchterman-Reingold layout.

Fields

niter: u32

Number of iterations (default: 500).

start_temp: Option<f64>

Starting temperature — maximum displacement per step (default: sqrt(V)).

grid: FrGrid

Grid acceleration mode (default: Auto).

weights: Option<Vec<f64>>

Edge weights (must be positive). None means all weights = 1.

bounds: FrBounds

Per-vertex coordinate bounds.

seed_coords: Option<Vec<(f64, f64)>>

If Some(coords), use as initial layout seed. Otherwise random init.

rng_seed: u64

RNG seed for random initialization (default: 42).
