    <h1>A "Fan" Line chart</h1>
    
    <p>
        This is an example of the filled range chart being used to create a "Fan" chart. Fan charts are used, for example, to illustrate
        growing uncertainty of future values. You can read about fan charts here: <a href="http://en.goldenmap.com/Fan_chart_(time_series)" rel="nofollow">http://en.goldenmap.com/Fan_chart_(time_series)</a>

    This goes in the documents header:

    Put this where you want the chart to show up:
    <pre class="code">

    [No canvas support]

    This is the code that generates the chart:
