applications using HTML5.

Getting Started
=================
```html
<html>
  <head>
    <title>SigPlot Standalone</title>
    <style>
      #plot {
        width: 600px;
        height: 400px;
      }
    </style>
  </head>
  <body>
    <div id="plot"></div>
    <script type="text/javascript" src="https://cdn.jsdelivr.net/npm/sigplot/dist/sigplot-debug.js"></script>
    <script type="text/javascript">
      var options = {};
      var plot = new sigplot.Plot(document.getElementById('plot'), options);
    </script>
  </body>
</html>
```

See [this jsFiddle](https://jsfiddle.net/ha09baqu/) as an example.  Additional
[examples and demos](http://sigplot.lgsinnovations.com/).

WebPack Quick Start
================================

These instructions assume you have Node.js/NPM correctly installed on your
system.

First install webpack:

```
npm install webpack -g
```

Then create a project for the SigPlot demo and install sigplot.

```bash
mkdir sigplot-webpack
cd sigplot-webpack
npm install sigplot
```

Next, create a file called `demo.js` with the following contents:

```javascript
let sigplot = require("sigplot");
let options = {};
let plot = new sigplot.Plot(document.getElementById('plot'), options);
```

Then, create a file called `index.html` with the following contents:

```html
<html>
  <head>
    <title>SigPlot Webpack</title>
    <style>
      #plot {
        width: 600px;
        height: 400px;
      }
    </style>
  </head>
  <body>
    <div id="plot"></div>
    <script type="text/javascript" src="bundle.js" charset="utf-8"></script>
  </body>
</html>
```

Use webpack to compile the bundle:

```bash
webpack ./demo.js bundle.js
```

Then open index.html in your webbrowser.
