我是 Shiny 的新手，我正在尝试使用d3TreeR HTML Widget来显示交互式树图

我使用了以下代码，它在 R 中完美运行：

library(htmlwidgets)
library(data.tree)
library(d3treeR)
budget_map <- read_excel(path = 'C:/Users/rahul/Desktop/30k foot view/Trader Dashboard Data Prep Sample.xlsx',sheet='v2',col_names = TRUE)
budget_treemap <- treemap(budget_map,index=c("Sales Agency","Agency","Advertiser"),vSize="Booked Revenue Net",vColor="Sales Agency",palette = "Set1",type="categorical")

ui <- fluidPage(
  d3tree2Output("au_budget_map")
)


server <- function(input,output){
    output$au_budget_map <- renderD3tree2({budget_treemap})
}

shinyApp(ui …
