    filter(continent != "Antarctica")

  ui <- fluidPage(
    tags$h2("Include tuimap in Shiny"),
    fluidRow(
      column(
        width = 3,
        actionButton(
          inputId = "refresh",
          label = "Refresh data"
        )

        width = 9,
        tuimapOutput(outputId = "my_map")
      )
    )
  )

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

    output$my_map <- renderTuimap({

      input$refresh

      # add a random numeric variable
      world$random <- sample(1:100, nrow(world), TRUE)

      # draw map
      tuimap() %>%
        add_map_data(
          data = world,
          mapping = aes(code = adm0_a3, label = name, value = random)
