jupyter - Simple plotly plots in R -

i can't seem figure out why can't plot simplest of dataframes in r using plotly. here's example want plot 2d scatter plot of dataframe named b:

b <- data.frame(cat=c(1, 2, 3, 4, 5), rabbit=c(1.1, 2.2, 3.3, 4.4, 5.5), dog=c(-1, -2, -3, -4, -5)) library(plotly) p <- plot_ly(b, x = cat, y = rabbit, mode= "markers") 

if print b, you'll see it's dataframe of 5 samples, column names cat, rabbit , dog, expected. when execute above in jupyter (don't know if matters), following error:

error in plot_ly(b, x = cat, y = rabbit, mode = "markers"): object 'rabbit' not found

traceback:

1. plot_ly(b, x = cat, y = rabbit, mode = "markers")

what doing wrong? far can tell, b legitimate dataframe, , cat , rabbit column names.
