Description

I am not sure whether this is the right forum to address the issue. Nevertheless, after quite some searching, I was unsuccessful to figure out a way to add a legend to a bubble chart, that reflects information on the bubble size in a chart like the one below.

library(plotly)
d <- diamonds[sample(nrow(diamonds), 1000), ]
plot_ly(d, x = carat, y = price, size = carat, mode = "markers")

I am looking for something a similar chart legend like in the picture attached.

If I am off topic here, please don´t hesitate to close the issue - a hint to a solution would be highly appreciated, though.

Best
Michael

Start by reproducing the supplied R example using plotly and compare its bubble sizing with the requested reference legend. Done means providing a bubble-size legend that reflects the carat values in the chart, with the expected behavior verified against the example.
