### [demo](http://shiny.john-coene.com/datamaps/)

```R

library(shiny)

ui <- fluidPage(

  textInput(

    "from",

    "Origin",

    value = "USA"

  ),

  textInput(

    "to",

    "Destination",

    value = "RUS"

  ),

  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)

 })

}

shinyApp(ui, server)

}
