Including googleVis output in a blogger post

It seems that you cannot include Google Visualisation Charts into a blog post directly. So, I tried to include the output of a googleVis function as a gadget, but also unsuccessfully. Although you can include gadgets into your site template, it doesn’t seem to work with blog posts. So, here is the trick which works for me: the iframe tag. The following geo map is included as

<iframe width="100%" height="400px" frameborder="0" src="http://dl.dropbox.com/u/7586336/blogger/AndrewGeoMap.html">
</iframe>

As you can see, the chart itself is actually displayed in a page hosted by Dropbox and only inserted into this post via the iframe-tag.

For those of you, who would like to replicate the plot of Hurricane Andrew, here is the R code:

library(googleVis)
options(gvis.plot.tag="chart")
library(googleVis)
AndrewGeoMap <- gvisGeoChart(Andrew, 
                             locationvar='LatLong', 
                             sizevar='Speed_kt',
                             hovervar='Category',
                             options=list(width=600,height=300,
                                          region='US', dataMode='Markers'))

plot(AndrewGeoMap)
