Leo, are you sure that 'factoid' is the word you want? The term stumped me for a long time, especially after I saw it used in different ways. So when I looked it up I was surprised...' '1. A piece of unverified or inaccurate information that is presented in the press as factual, often as part of a publicity effort, and that is then accepted as true because of frequent repetition'.
Looking at your graph, I think you mean 'factette' or something like that

. microfact, factoweinie, factacito ????
