ggplot2 ggalt geom_encircle() sample plot of average colour

Given a CSV file saved to ~/Documents/sample-hour-count-colorname.csv

hour,count,colour
1,5,red
1,2,green
2,10,red
2,3,blue
3,2,green
3,5,red

Then the following R code creates an encircled plot

hh = read_csv("~/Documents/sample-hour-count-colorname.csv")
gg <- ggplot(hh, aes(hour, count))
p <- gg + geom_encircle(aes(group=colour,colour=I(colour))) + geom_point()
p

results in the following output graph

Graph (has flickr embed which could break in the future)

Fragment: Tools of Production – ggalt and encircling scatterplot points in R, ggplot2 and Python <— geom_encircle() looks great to circle photos average colour?!? also geom_lollipop and dumbell! both look useful
