* - ezcGraphRendererOptions
* - ezcGraphRenderer2dOptions
* - ezcGraphRenderer3dOptions

* $graph->options->lineThickness = 3;
*
* // Add data

*
* $graph->render( 400, 150, 'tutorial_line_chart.svg' );
* </code>
*
* @property float $lineThickness
* Thickness of chart lines
* @property mixed $fillLines
* Status wheather the space between line and axis should get filled.
* - FALSE to not fill the space at all.
* - (int) Opacity used to fill up the space with the lines color.
* @property int $symbolSize
* Size of symbols in line chart.
* @property ezcGraphFontOptions $highlightFont
* Font configuration for highlight tests
* @property int $highlightSize
* Size of highlight blocks
* @property bool $highlightLines
* If true, it adds lines to highlight the values position on the
* axis.
