ruviz

High-performance 2D plotting library for Rust combining matplotlib's ease-of-use with Makie's performance.

Quick Start

use ruviz::prelude::*;

let x: Vec<f64> = (0..50).map(|i| i as f64 * 0.1).collect();
let y: Vec<f64> = x.iter().map(|&x| x * x).collect();

Plot::new()
    .line(&x, &y)
    .title("Quadratic Function")
    .xlabel("x")
    .ylabel("y = x²")
    .save("plot.png")?;

Features

🛡️ Safety & Quality

• Zero unsafe in public API
• Strong type system prevents runtime errors
• Comprehensive error handling with Result types
• Memory-safe by design

📊 Plot Types

Basic: Line, Scatter, Bar, Histogram, Box Plot, Heatmap Distribution: Violin, KDE, ECDF Composition: Pie, Donut Continuous: Contour Polar: Polar Plot, Radar Chart Error: Error Bars (symmetric/asymmetric)

🎨 Publication Quality

• High-DPI export: 72, 96, 300, 600 DPI for print
• Multiple formats: PNG, SVG (SVG in development)

For minimal builds: default-features = false

Examples

Basic Line Plot

use ruviz::prelude::*;

let x = vec![0.0, 1.0, 2.0, 3.0, 4.0];
let y = vec![0.0, 1.0, 4.0, 9.0, 16.0];

Plot::new()
    .line(&x, &y)
    .title("My First Plot")
    .save("output.png")?;

Multi-Series with Styling

use ruviz::prelude::*;

let x = vec![0.0, 1.0, 2.0, 3.0, 4.0];

Plot::new()
    .line(&x, &x.iter().map(|&x| x).collect::<Vec<_>>())
    .label("Linear")
    .line(&x, &x.iter().map(|&x| x * x).collect::<Vec<_>>())
    .label("Quadratic")
    .line(&x, &x.iter().map(|&x| x.powi(3)).collect::<Vec<_>>())
    .label("Cubic")
    .title("Polynomial Functions")
    .xlabel("x")
    .ylabel("y")
    .theme(Theme::publication())
    .save("polynomials.png")?;

Subplots

use ruviz::prelude::*;

let plot1 = Plot::new().line(&x, &y).title("Line").end_series();
let plot2 = Plot::new().scatter(&x, &y).title("Scatter").end_series();
let plot3 = Plot::new().bar(&["A", "B", "C"], &[1.0, 2.0, 3.0]).title("Bar").end_series();
let plot4 = Plot::new().histogram(&data).title("Histogram").end_series();

subplots(2, 2, 800, 600)?
    .suptitle("Scientific Analysis")
    .subplot(0, 0, plot1)?
    .subplot(0, 1, plot2)?
    .subplot(1, 0, plot3)?
    .subplot(1, 1, plot4)?
    .save("subplots.png")?;

Large Dataset

use ruviz::prelude::*;

// 100K points with parallel rendering (enable "parallel" feature)
let x: Vec<f64> = (0..100_000).map(|i| i as f64).collect();
let y: Vec<f64> = x.iter().map(|&x| x.sin()).collect();

Plot::new()
    .line(&x, &y)
    .title("Large Dataset")
    .save("large.png")?;

Animation

use ruviz::prelude::*;
use ruviz::animation::RecordConfig;
use ruviz::record;

let x: Vec<f64> = (0..100).map(|i| i as f64 * 0.1).collect();
let config = RecordConfig::new().max_resolution(800, 600).framerate(30);

record!(
    "wave.gif",
    2 secs,
    config: config,
    |t| {
        let phase = t.time * 2.0 * std::f64::consts::PI;
        let y: Vec<f64> = x.iter().map(|&xi| (xi + phase).sin()).collect();
        Plot::new()
            .line(&x, &y)
            .title(format!("Wave Animation (t={:.2}s)", t.time))
            .xlim(0.0, 10.0)
            .ylim(-1.5, 1.5)
    }
)?;

Why ruviz?

Rust's plotting ecosystem has several options, but each has trade-offs:

ruviz fills the gap with:

• High-level API: matplotlib-style Plot::new().line().title().save() - no boilerplate
• Pure Rust: No Python, JavaScript, or external runtime needed
• Built-in plot types: 15+ plot types out of the box (violin, KDE, radar, etc.)
• Publication quality: Professional themes and high-DPI export

// plotters: ~30 lines for a simple line plot
// ruviz: 4 lines
Plot::new()
    .line(&x, &y)
    .title("My Plot")
    .save("plot.png")?;

Development

# Clone repository
git clone https://github.com/Ameyanagi/ruviz.git
cd ruviz

# Setup pre-commit hooks (recommended)
make setup-hooks

# Run code quality checks
make check

# Run tests
cargo test --all-features

# Run examples
cargo run --example basic_example --release

# Run benchmarks
cargo bench --all-features

The pre-commit hooks will automatically run cargo fmt --check and cargo clippy before each commit to ensure code quality.
