Splom fig not showing any markers

Hello,
The sample code for the splom is not showing the scatter markers for me. I get all the different frames but no markers.

Has this issue been raised by anyone?

library(plotly)
library(dplyr)
df <- read.csv('https://raw.githubusercontent.com/plotly/datasets/master/iris-data.csv')
pl_colorscale=list(c(0.0, '#19d3f3'),
                   c(0.333, '#19d3f3'),
                   c(0.333, '#e763fa'),
                   c(0.666, '#e763fa'),
                   c(0.666, '#636efa'),
                   c(1, '#636efa'))
axis = list(showline=FALSE,
            zeroline=FALSE,
            gridcolor='#ffff',
            ticklen=4)

df %>%
    plot_ly() %>%
    add_trace(
        type = 'splom',
        dimensions = list(
            list(label='sepal length', values=~sepal.length),
            list(label='sepal width', values=~sepal.width),
            list(label='petal length', values=~petal.length),
            list(label='petal width', values=~petal.width)
        ),
        text=~class,
        marker = list(
            color = as.integer(df$class),
            colorscale = pl_colorscale,
            size = 7,
            line = list(
                width = 1,
                color = 'rgb(230,230,230)'
            )
        )
    ) 

Commencez par exécuter l’exemple R fourni pour le plotly.R splom trace et vérifiez comment les frames et les marqueurs de dispersion sont rendus. L’issue est résolue lorsque l’exemple affiche les marqueurs attendus dans les frames splom.
