Looking into this further, this is very strange, since the font-size is being applied to the title, but has a different effect. I'm guessing my ignorance of the finer points of CSS is to blame. For now, to fix, you can do something like this.

library(shiny)
library(dplyr)
library(rcdimple)
library(htmltools)

## INTERACTIVE APP 

ex_data <- read.delim(
  "http://pmsi-alignalytics.github.io/dimple/data/example_data.tsv"
)

colnames(ex_data) <- gsub("[.]","", colnames(ex_data))#eliminate . to avoid confusion in javascript



server <- shinyServer(function(input, output) {

  output$distPlot <- renderDimple({

    #groupvars <- input$checkGroup

    d1 <- dimple(
      y = input$ChoiceA,
      x = "UnitSales",
      groups = input$checkGroup,
      data = ex_data,
      type = "bubble"
    ) %>%
      xAxis( type = "addMeasureAxis"
             , fontSize = "120%"
             , fontFamily = "monospace") %>%
      yAxis( type = "addMeasureAxis" 
             , fontSize = "120%"
             , fontFamily = "monospace") %>%
      add_legend()

    d1$x$options$tasks <- list(htmlwidgets::JS(
'
function(){
  d3.select(this).selectAll(".dimple-axis.dimple-title")
    .style("font-size","200%")
}
'
    ))

    d1
  })


}
)


ui <- shinyUI(fixedPage(

  titlePanel("title-title"),

  fixedRow(
    column(width = 2,  

           selectInput("ChoiceA", "ChoiceA:", choices = c("OP"="OperatingProfit",  
                                                          "GP"="GrossProfit", 
                                                          "P"="Price"), selected="OperatingProfit")

           ,

           checkboxGroupInput("checkGroup", label = h3("Include Group"), 
                              choices = list("1. SKU" = "SKU", "2. Channel" = "Channel", "3. Brand" = "Brand"),
                              selected = c("SKU", "Channel"))



    ),        

    column(width = 10,      

           mainPanel(
             dimpleOutput("distPlot", height = 700, width = 900)
           )
    )
  )



)
)


shinyApp(ui = ui, server = server)

Alternately, if you want to use tags$head, you can style with the CSS selector .dimple-axis.dimple-title.
