    <p>
        Graph2d can load data from an <code>Array</code>, a <code>DataSet</code> (offering 2 way data binding), or a <code>DataView</code> (offering one way data binding).
        Objects are added to this DataSet by using the <code>add()</code> function.
        Data points must have properties <code>x</code>, <code>y</code>, and <code>z</code>,
        and can optionally have a property <code>style</code> and <code>filter</code>.
    <p>
        Graph2d can be provided with two types of data:
