TheDraw was used mostly in the BBS scene to create ASCII/ANSI art for the BBS's log in screen and menus. There was an entire sub-community of artists back then.

To be fair, the website is a diagram tool that outputs ASCII, while TheDraw more more like a ASCII/ANSI illustration tool.

I didn't find any galleries of ANSI art out there but this page has a few screenshots: http://icodeforfood.com/shockwave-bbs/
