Your example plots don't really indicate what is being plotted in terms of principal components. Are they scores? Are they loadings? Are they something else? What is the central point where the lines converge? Can you indicate with more clarity what it is that you want to plot?

Scatterplots of loadings or scatterplots of scores are easy, as PROC PRINCOMP will output these quantities, and PROC SGPLOT will plot them. Connecting the data values to some centroid is something that I don't think is built into SAS, and so you'd have to figure out how to do that yourself.
