  ),

  actionButton(

    "submit",

    "Draw arc"

  ),

  datamapsOutput("map")

)

server <- function(input, output){

  arc <- reactive({

    data.frame(from = input$from, to = input$to)

  })

 output$map <- renderDatamaps({

   datamaps()

 })

 observeEvent(input$submit, {

   datamapsProxy("map") %>%

     add_data(arc()) %>%

     update_arcs_name(from, to)

 })
