5592  * @fileoverview Creates an interactive, zoomable graph based on a CSV file or
5593  * string. DateGraph can handle multiple series with or without error bars. The
5594  * date/value ranges will be automatically set. DateGraph uses the
5595  * &lt;canvas&gt; tag, so it only works in FF1.5+.

5598   Usage:
5599    <div id="graphdiv" style="width:800px; height:500px;"></div>
5600    <script type="text/javascript">
5601      new DateGraph(document.getElementById("graphdiv"),
5602                    "datafile.csv",
5603                      ["Series 1", "Series 2"],
5604                      { }); // options
5605    </script>
5606
5607  The CSV file is of the form
5608
5609    YYYYMMDD,A1,B1,C1
5610    YYYYMMDD,A2,B2,C2
5611
5612  If null is passed as the third parameter (series names), then the first line
5613  of the CSV file is assumed to contain names for each series.
5614
5615  If the 'errorBars' option is set in the constructor, the input should be of
5616  the form
5617
5618    YYYYMMDD,A1,sigmaA1,B1,sigmaB1,...
5619    YYYYMMDD,A2,sigmaA2,B2,sigmaB2,...
5620
5621  If the 'fractions' option is set, the input should be of the form:
5622
5623    YYYYMMDD,A1/B1,A2/B2,...
5624    YYYYMMDD,A1/B1,A2/B2,...
5625
5626  And error bars will be calculated automatically using a binomial distribution.
