Hm too short editing time so x2
@Just-B hm medieval typography and/or posters in romanticism generally are considered Graphic Design or!?, in such manner cave paintings too 
also think in every of those movements there were illustrators or at least their sketches can be considered as concept graphic design intended for particular audience [1]
@IbrahimAhmed it was suggestion to use some free database engines that can crawl wikipedia … if want more heavy tool there are some stalled public projects about semantic db engines [1][1][1] eg. among which is also the Topic Maps standard [2][2][2] still I am not sure where except at seealso.org can be explored similar tools freely, or normally You can try visualized crawling through commercial engines - eg. [3][3][4][4] tho not sure whether these can be fed with web data or have web analytics tools …
- .. hm earlier there was one simple mindmap alike engine for wiki, but cant remember the name, it was like flat gui with wired topic nodes by similarity, tried to find it coz it will come handy for me too, but for now I’ll need to stick to the limited seealso alike freebies [5][5][5] IF SOMEONE HAS BETTER PROPOSAL BE FRIENDLY AND SHARE IT …
… anyway if You go so vast, think it would be useful to link AAAtlas alike data too as add agencies overlook, or You can include some public libraries info [6] finally and ideally this kind of project should be pushed by some Graphic Design Association or Museum coz it would be well funded by federal money in eU or usA, yet You can stir momentum for Open Source Project so would get help and fundraising coz it would be time consuming effort but also extra egotripping spin if push it alone, altho as idea sounds good, try maybe open dedicated eforum for the project, but do use some neo4j alike portal as main page and probably people will start contributing …
