Research direction

Start by reproducing the supplied Shiny example with renderPlotly, plotlyOutput, and geom_text_repel, then compare it with the working plotOutput version. Trace how plotly handles ggplot2 layers and identify the entry point where ggrepel support is missing. Done means the example renders the repelled labels through plotlyOutput without breaking existing plotly behavior.

Written by the indexing model from the issue text.

Description

I would like plotly to support ggrepel::geom_text_repel.
I prepare the following shiny that works with plotOutput but not with plotlyOutput :

library(shiny)
library(plotly)
library(ggplot2)
library(ggrepel)
library(bslib)

ui <- page_sidebar(
  title = "Hello Shiny!",
  sidebar = sidebar(
    selectizeInput(
      inputId = "Test",
      label = "Tests to show",
      choices = paste("Test",1:272),
      multiple = TRUE
    )
  ),
  plotlyOutput(outputId = "distPlot")
)

server <- function(input, output) {
  
output$distPlot <- renderPlotly({
    
  x<-faithful
  x$test<-paste("Test",1:272)
  
  ggplot(x,aes(x=eruptions,y=waiting))+
    geom_point()+
    geom_text_repel(data = x[match(input$Test,x$test),],
                    aes(label = test),
                    color="blue")
    
  })
  
}

shinyApp(ui = ui, server = server)
