title: Google charts in R Shiny are not working from Rstudio on windows
body: <p>I am struggling to run google charts in R Shiny. The following app runs perfectly fine on our local Shiny Server. However, when I run the same code from R Studio on Windows PC, google chart does not appear. Any thought? Thanks!</p>
  
  <pre><code>## app.R ##
  library(shiny)
  library(shinydashboard)
  suppressPackageStartupMessages(library(googleVis))
  
  ui &lt;- dashboardPage(
    dashboardHeader(title = "Basic dashboard"),
    dashboardSidebar(),
    dashboardBody(
  
      fluidRow(box(htmlOutput("plot", height = 250)))
    )
  )
  
  server &lt;- function(input, output) {
    set.seed(122)
    histdata &lt;- rnorm(500)
  
    output$plot &lt;- renderGvis({ gvisBubbleChart(Fruits, idvar="Fruit", 
                                                xvar="Sales", yvar="Expenses",
                                                colorvar="Year", sizevar="Profit",
                                                options=list(
                                                  hAxis='{minValue:75, maxValue:125}')) })
  
  }
  
  shinyApp(ui, server)
  </code></pre>
