Gust

A charting library for rust!

Build Status Crates.io

Disclaimer This is still very much a work in progress! APIs are very unstable and subject to change. Contributions and suggestions are welcomed and greatly appreciated!


What is Gust

Gust is a small charting crate to make it really easy to build simple interactive data visualizations in rust. It also serves as a partial Vega implementation that will (hopefully) become more complete over time.


Gust allows you to render the actual visualizations themselves using D3.js, (meaning they're interactive!) as well as providing the flexibility to directly render the underlying JSON specification for Vega.

Currently Implementations

Currently, Gust supports only 3 charts so far:

  1. Bar Charts
  2. Stacked Bar Charts
  3. Line Charts

More will be coming soon! If you're interested in contributing your own, just make a pull request. Cheers!

Why did you do this in rust?

Installation

gust = "0.1.4"

Samples and Sample Usage

    use backend::bar_chart::BarChart;
    use frontend::write::render_graph;

Sample Bar Chart

     let mut b = BarChart::new();
        let v = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L"];
        for i in 0..10 {
            b.add_data(v[i].to_string(), (i * i * i) as i32);
        }
        render_graph(&b, FileType::HTML).unwrap();

Result: gust_build/html/bar_chart.html

Stacked Bar Chart example

use backend::stacked_bar_chart::StackedBarChart;

let mut b = StackedBarChart::new();
        for i in 0..10 {
            b.add_data(i, i * i, 1);
            b.add_data(i, i + i, 0);
        }
        render_graph(&b, FileType::HTML).unwrap();

Result: gust_build/html/stacked_bar_chart.html

Special Mentions

The rendering is all handled by Vega: https://vega.github.io/

You can’t perform that action at this time.
