R Plotly中的3D气泡图

Question

I am struggling with developing a 3D bubble chart in R plotly. Plotly has a nice tutorial in python, but I have been unable to replicate in R.

library(plotly)
plot_ly(mtcars, x=mpg, y=cyl, z=disp, type='scatter3d', mode='markers',
        marker=list(sizemode='diameter', sizeref=750, size=hp, color=drat, 
                    colorscale = 'Viridis'))

Answer 1

library(plotly)
plot_ly(mtcars, x=mpg, y=cyl, z=disp, type='scatter3d', mode='markers',
        sizemode='diameter', size=hp, color=drat, colorscale = 'Viridis')
