At the end of March Google released a new version of the Chart Tools API with new options for point shapes and line brushes. The arguments are called pointShape and lineDashStyle and can be set directly via googleVis.

We published googleVis 0.5.2 on CRAN yesterday with added examples for those new options in gvisLineChart and gvisScatterChart. Note, these options can be used with most chart types as well, also in combination. Visit the Google documentation for more details.
