I worked for a company that made data visualization software a couple years back (basically a Tableau type thing, but specific to one industry). Even though our end-users were analysts, we still had "trainers" who we paid to show up in-person, on-site, to teach the end-users how to read all the types of visualizations that our software could generate. The visualizations weren't tremendously complex, but when most real-world analysts still spend most of their time in Excel, a brief explanation is still required for the end-users to actually buy-in.
