- “This is not an introduction to R”
- “Visualisation is a useful way of representing data”
- “We are going to study diamonds!”
- Plots in ggplot2 are build by adding layers
- “Data can be plottet as something other than position”
- “Types of plots are determined by
geom_functions”
- “Categorical data, aka factors can control the order of data in
plots”
- “ggplot makes it easy to make many different types of plots”
- “ggplot have many useful extensions”
- “Facetting can make busy plots more understandable”
- “Grid facetting in two dimensions allows us to plot even more
variables”
- “Pie charts are a bad idea!”

- “Play around to find the colours you like”
- “EVERYTHING in the plot can be customized”
