/**
 * @fileoverview Creates an interactive, zoomable graph based on a CSV file or
 * string. DateGraph can handle multiple series with or without error bars. The
 * date/value ranges will be automatically set. DateGraph uses the
 * &lt;canvas&gt; tag, so it only works in FF1.5+.
 * @author danvdk@gmail.com (Dan Vanderkam)

  Usage:
   <div id="graphdiv" style="width:800px; height:500px;"></div>
   <script type="text/javascript">
     new DateGraph(document.getElementById("graphdiv"),
                   "datafile.csv",
                     ["Series 1", "Series 2"],
                     { }); // options
   </script>

 The CSV file is of the form

   YYYYMMDD,A1,B1,C1
   YYYYMMDD,A2,B2,C2

 If null is passed as the third parameter (series names), then the first line
 of the CSV file is assumed to contain names for each series.

 If the 'errorBars' option is set in the constructor, the input should be of
 the form

   YYYYMMDD,A1,sigmaA1,B1,sigmaB1,...
   YYYYMMDD,A2,sigmaA2,B2,sigmaB2,...

 If the 'fractions' option is set, the input should be of the form:

   YYYYMMDD,A1/B1,A2/B2,...
   YYYYMMDD,A1/B1,A2/B2,...

 And error bars will be calculated automatically using a binomial distribution.

 For further documentation and examples, see http://www/~danvk/dg/
