r - GoogleVis does not show chart in RStudio -

i trying use googlevis-0.5.10 rstudio 0.99.473 on windows 7. can generate charts fine, opened in new browser window. code simple, no options set:

linechart <- gvislinechart(data,                        options = list(                          selectionmode = "multiple",                          focustarget = "category",                          tooltip = "{ trigger : 'focus', aggregationtarget: 'auto' }")                        ) plot(linechart) 

i have tried call viewer manually providing url opened browser window:

rstudio::viewer("http://127.0.0.1:10529/custom/googlevis/linechartidc6837e37021.html") 

but shows empty screen:

i think kind of security issue when right click rstudio viewer window , open web inspector, see there javascript error:

failed load resource: unable init ssl context:  https://www.google.com/jsapi?callback=displaychartlinechartidc6837e37021 

if right, there way instruct rstudio trust content www.google.com domain? or, if wrong, how can fix problem?

thank you.

i think flash player not enabled. in chrome type:

chrome://plugins 

and check flash player checkbox , try again.
