Crate eunoia 

A Rust library for creating area-proportional Euler and Venn diagrams.

A fit has two stages:

1. Multi-dimensional scaling places fixed-size shapes.
2. Numerical optimization refines the shapes against the chosen loss.

Example

use eunoia::{DiagramSpecBuilder, Fitter, InputType};
use eunoia::geometry::shapes::Circle;

let spec = DiagramSpecBuilder::new()
    .set("A", 5.0)
    .set("B", 2.0)
    .intersection(&["A", "B"], 1.0)
    .input_type(InputType::Exclusive)
    .build()
    .expect("Failed to build diagram specification");

let layout = Fitter::<Circle>::new(&spec).fit().unwrap();
