geom_GeomCircle() has yet to be implemented in plotly.

Hello,

In short, plotly currently doesn't support geom_circle(), and it would be great to be able to do so.

In this example, I am making a plot of several overlapping circles corresponding to their variable number's size (in this case, tonnes of carbon). It would be great to use plotly to create a hover function that displays each circle's total number of tonnes, for easy reading by the user. I would like to use renderPlotly({}) instead of renderPlot({}) in the following example.

Thanks!

output$carbon_stores_summary_plot <- renderPlot({

        ggplot(data = carbon_data)+
          coord_fixed()+
          geom_circle(aes(x0 = 0, y0 = 1,
                          r = 1),
                      fill = "#7ECBEF",
                      color = NA,
                      n = 10000)+
          geom_circle(aes(x0 = 0, y0 = V/B,
                          r = V/B),
                      fill = "#357D57",
                      color = NA,
                      n = 5000)+
          geom_circle(aes(x0 = 0, y0 = I/B,
                          r = I/B),
                      fill = "#8c007a",
                      color = NA,
                      n = 5000)+
          theme_void()
})

從提供的 geom_circle 範例開始，並比較 plotly.R 中目前的 renderPlot 和 renderPlotly 路徑。確定圓形、其大小以及要求的 hover 值應如何表示；當重疊的圓形透過 renderPlotly 繪製，並向使用者呈現每個圓形的總值時，即表示完成。
