I am fascinated by dynamic or interactive ggplot graphs. I found some easy hover options with ggiraph at https://davidgohel.github.io/ggiraph/ Here is a MWE for R markdown:
---
title: "Hover"
author: "Author"
output: html_document
---
## Hover ggplot2
```{r, warning=FALSE, message=FALSE}
library(ggplot2)
library(ggiraph)
data <- mtcars
data$carname <- row.names(data)
gg_point = ggplot(data = data) +
geom_point_interactive(aes(x = wt, y = qsec, color = disp,
tooltip = carname, data_id = carname)) +
theme_minimal()
girafe(ggobj = gg_point)
```
Is there any possibility to show a small image or icon when hover over a datapoint in a ggplot in markdown? I wonder how and where I would store these images. I would like to give every data point a specific image. I am working on famous painters, i.e. assume that I have very few data points in a scatterplot. Thus when people hover on "The Scream", they should see a little version of https://en.wikipedia.org/wiki/List_of_most_expensive_paintings#/media/File:The_Scream_Pastel.jpg
