Doughnut chart in R with googleVis
The guys at Google continue to update and enhance the Chart Tools API. One new recent feature is a pie chart with a hole, or as some call them: donut charts.Thankfully the new functionality is being achieved through new options for the existing pie chart, which means that those new features are available in R via googleVis as well, without the need of writing new code.

"One new recent feature is a pie chart with a hole" this should be listed as a bug, not a feature
Thank you for this Markus - is it possible to do multilevel donut plots with this?
For example:

No, unfortunately I don't think so.
Oh well. Will you consider this an informal feature request? :-)
Well, googleVis is only an interface to the Google Chart Tools and as long as the API doesn't support this feature there is little I can do.
Understood. I've submitted a feature request to the Chart Tools issue tracker. It's a long shot but I'll keep my fingers crossed.
