Using geoms for explanatory plots
Let's focus on producing beautiful and effective explanatory plots. In the next couple of exercises, you'll create a plot that is similar to the one shown in the video using gm2007, a filtered subset of the gapminder dataset.
This type of plot will be in an info-viz style, meaning that it would be similar to something you'd see in a magazine or website for a mostly lay audience.
A scatterplot of lifeExp by country, colored by lifeExp, with points of size 4, is provided.

Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Add a geom_segment() layer
ggplot(gm2007, aes(x = lifeExp, y = country, color = lifeExp)) +
geom_point(size = 4) +
___(___(xend = ___, yend = ___), size = 2)
