A Unicode terminal plotting library for Rust.

This crate provides canvas-based rendering of plots using Unicode characters (braille, block elements, ASCII, dot, and density characters) for display in terminal emulators. It is a Rust port of the rendering layer from unicode_plot.rb and UnicodePlots.jl.

Quick start

use unicode_plot::{barplot, BarplotOptions};

let plot = barplot(
    &["cat", "dog", "parrot"],
    &[30, 45, 12],
    BarplotOptions::default(),
).unwrap();

let mut output = Vec::new();
plot.render(&mut output, false).unwrap();
let text = String::from_utf8(output).unwrap();
assert!(text.contains("dog"));
