Hello, I am doing a principle component analysis on a dataset with a lot of different variables and have constructed a biplot of the data. Unfortunately, as can be seen on the attached image, the biplot is very messy, cluttered, and hard to read. I have performed a few modifications including outlier removal from a few of the variables, which has made the plot better, however it still is too cluttered to read the variable names. Is there any further improvment that can be made to the attached plot and if so what steps should I take?
Thanks, Derek
