Google-style Gauge Chart with D3

A re-creation of Google Charts's Gauge chart using D3. Only the basics are included: a label and a value.

Installation

1. Include D3: <script src="https://d3js.org/d3.v5.min.js"></script>
2. Include JS: <script src="https://unpkg.com/d3-gauge-chart"></script>
3. Include CSS: <link rel="stylesheet" href="https://unpkg.com/d3-gauge-chart/d3-gauge-chart.css">

Usage

1. Create a new SVG element in your HTML. Make sure it has an id, width, and height. For best results, make it square.

2. Call the function:

gaugeChart({
  el: '#chart',
  label: 'Memory',
  value: 73,
  min: 0,   // optional
  max: 100, // optional
});
