Lightweight Doughnut Chart Library for JavaScript

This is a very simple library without bells and whistles, it has no dependencies.

It generates a SVG figure for the browser to render, and that's all it does.

The API is very simple. First you need to find an element to insert the graph on, e.g.:

var chart_div = document.getElementById("mychart")

Then you instantiate the class:

 var mychart = new DonutChart(chart_div, {
    r: 60,
    stroke: 16,
    scale: 100,
    items: [
        { label: "A", value: .2 },
        { label: "B", value: .1 },
        { label: "C", value: .5 },
    ]
})

And if you need to, you can update the values:

mychart.update({
    items: [
        { label: "J", value: .4 },
        { label: "Q", value: .3 },
    ]
})

Have fun!
