Spider and Parallel Charts in R with the ggvanced Package
Motivation
During one of my Data Analysis projects, I found myself in need of an effective way to compare groups across several variables at once. Of course, bar charts came to mind first, but I wanted something more eye-catching, something more interesting. After browsing the web a bit, I settled on two prime candidates – a spider chart and a parallel chart.
After this, I usually just find a dedicated R package producing the needed visualizations, but this time, this approach left me empty-handed.
A LIE – more experienced R users might say! Such visualizations can already be obtained using packages such as fsmb and ggradar for radar charts and ggally for parallel plots.
However, aside from just performing the ranked comparison of groups across variables, I also wanted to simultaneously display the range of values for each variable. And, you guess it, none of the aforementioned packages offered this. So, I decided to build my own
