Although manga is not a traditional medium, I think one could say its a (visual), derivative of calligraphy or the old painters (and thus worthy on this forum:).
I would like to introduce those who aren't familiar with it to a graphic novel (chic words!), or manga about Miyamoto Musashi. Its a series that's been going for years and is still ongoing.
Being a story its fiction but somewhat (and in the general theme a whole lot), related to Japanese history. Written by the creator of Slam Dunk (famous name from the Shounen magazine (if I recall correctly. )), Takehiko Inoue.
I think for everyone who's interested in Japanese history, and especially weapons and the feudal era this series is very interesting. Although manga has a kind of negative undertone being something only for youth (outside Japan that is, or at least where i live), I think this series can entertain and interest people of all ages. The artwork is absolutely top notch and the story is at times action packed but overall a fantastic story, that's still not finished.
For me personally this is one of my all time favorite and most memorable manga i know of and follow.
Now a slight disclaimer as its simply impossible for me, and i assume most people outside Japan (except those who started buying and following this manga from the start in Japan), to afford and read all chapters on paper.
Because of that i read it online.
Please have a look/Begin reading!
