        idvar="Country",timevar= "Year", 
        xvar = "New_inf",yvar = "Num_TB_HIV",
        sizevar = "HIV_size_variable",
        options = list( showChartButtons=TRUE))

What can you do with R?

Spatial vizualization (Maps)

R code

MozMap <- gvisMap(Sim_MozData, locationvar="latlong" ,tipvar ="TipV", 
                  options=list(showTip=TRUE, showLine=TRUE, enableScrollWheel=TRUE,
                               mapType='terrain', useMapTypeControl=TRUE))

What can you do with R?

Combining plots

R code

MapWd <- gvisGeoChart(UNAIDS2015Data, "Country", "HIV_prev_1549")

DataTable <- gvisTable(UNAIDS2015Data)

MapTable <- gvisMerge(DataTable, MapWd, horizontal=TRUE)

What can you do with R?

Tabular visualization (pivot table)
