 <h2>Graph2D | Performance</h2>
 <div style="width:700px; font-size:14px; text-align: justify;">
    This example shows the some of the graphs outlined on the right side using the <code>yAxisOrientation</code> option within the groups.
    We also show a few more custom styles for the graphs. Finally, the legend is manually positioned. Both the left and right axis
    have their own legend. If one of the axis is unused, the legend is not shown. The options for the legend have been split
    in a <code>left</code> and a <code>right</code> segment. The default position of the left axis has been changed.


    This example is a test of the performance of the Graph2D. Select the amount of datapoints you want to plot and press draw.
    You can choose between the style of the points as well as the interpolation method. This can only be toggled with the buttons.
