This is the first part of a two part article on using R and the ggplot2 package to visualise patent data. In a previous article we looked at visualising pizza related patent activity in Tableau Public. In this article we look at how to plot our pizza dataset using the ggplot2 package in RStudio. You do not need to know anything about R to follow this article. You will however need to install RStudio Desktop for your operating system (see below).
