    fluidRow(
      column(
        width = 3,
        checkboxGroupInput(
          inputId = "year",
          label = "Year:",
          choices = c(1999, 2008),
          selected = c(1999, 2008)
        )

        tuichartOutput(outputId = "my_chart")
      )
    )
  )

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

    output$my_chart <- renderTuichart({

      data <- filter(mpg, year %in% input$year) %>%
        count(manufacturer)

      tuichart("bar") %>%
        add_data(data, aes(x = manufacturer, y = n)) %>%
        tui_chart(title = "My cool chart") %>%
