Google Charts CSS

When adding a google charts object to a layout, the rendering of the chart is limited in height and width to 432 x 200. I looked at the CSS that generates the chart itself. Even if i adjust the size of the chart in the options or the class settings, the chart section remains very small (and illegible). is there a better way to target the class of the chart to control the size of the graphic?

I think the charts fill their parent container.
