Since the images in the article are rather small, I found the original document (linked at bottom) and scaled up some of the more interesting charts. They're assuming companies that IPOed in the last few years are still considered "Unicorns", which I find rather questionable. Anyway, it is quite nice to see all these companies in one place so here's the all the interesting charts:
