Adding an arrow in a googleVis bubble chart

Question

I have the following plot:

I have a requirement to add an arrow from the Old Value to the new Value. Is there any way i can add an arrow in a bubble chart or is there a way i can superimpose an arrow onto the bubble chart like we can do in ggplot

Code for my gvis bubble chart :

bub <- gvisBubbleChart(
            ttt2, 
            idvar = "ID",
            xvar = "x", yvar = "y",
            colorvar = "color",sizevar = "size",
            options = list(
              width = 700, height = 500,bubble.textStyle = '{fontSize : 1}',
              vAxis = "{title:'Low Risk Region...................High Risk Region'}",
              colors="['#FE642E','#58FA82', '#819FF7','#FF0000']"
            )
          )

Sample Data :
