Hitler is also on the map. "Famous" isn't the word used on the webpage - that can sometimes mean "celebrated". The word they use is "notable", which is perhaps more appropriate when talking about people who have committed heinous acts.
Hitler might be the most (in)famous person ever to have lived and so much so that his name has become a synonym for evil (colloquially). There is a reason that every page on Wikipedia is 6 clicks away from his article.
