r plotly equivalent ggplot2 to python

How to manually set the labels of the points in a plotly?

library(ggplot2)
library(plotly)
p <- iris %>% 
 ggplot(aes(Sepal.Length, Sepal.Width, color = Species)) +
 geom_point() +
 labs(
  title = "A graph",
  x = "Sepal Length (cm)",
  y = "Sepal Width (cm)",
  color = "Species of Iris"
) 

ggplotly(p)

The axis are correctly labelled, but the data is not. R output

Here is an example of how it works in Python

https://plotly.com/python/figure-labels/

import plotly.express as px

df = px.data.iris()
fig = px.scatter(df, x="sepal_length", y="sepal_width", color="species",
                 labels={
                     "sepal_length": "Sepal Length (cm)",
                     "sepal_width": "Sepal Width (cm)",
                     "species": "Species of Iris"
                 },
                title="Manually Specified Labels")
fig.show()

result of popups

Here's an example using the text aesthetic that ggplot doesn't use, but which gets passed along to plotly, and glue::glue as an alternative to paste0.

library(ggplot2)
library(plotly)
p <- iris %>% 
  ggplot(aes(Sepal.Length, Sepal.Width, color = Species)) +
  geom_point(aes(text = glue::glue(
    "Species of iris={Species}\n",
    "Sepal Width (cm)={Sepal.Width}"))) +
  # alternative using base paste0:
  #geom_point(aes(text = paste0("Species of iris=", Species, "\n",
  #                             "Sepal Width (cm)=", Sepal.Width))) +
  labs(
    title = "A graph",
    x = "Sepal Length (cm)",
    y = "Sepal Width (cm)",
    color = "Species of Iris"
  ) 

ggplotly(p, tooltip = 'text')
