## How not to make an evergreen review graph

In this post I am inspired by two tweets, mainly this one and also this one. Since the total number of articles every year is increasing, no matter which subject you choose, the curve representing number of articles as a function of year of publication will probably look exponential, so one should not use such graphs to impress readers. At least I’m not impressed, I’m more amused by such graphs now that there’s a hashtag for them.

I shall use an rOpenSci package for getting some data about number of articles about a query term, and to do a graph that’s not an evergreen review graph!
