adding to this i would suggest

and other similar molecular dynamics simulations
indeed the role of models and representations is central from the circles of Tyco Brae to the elipses of Kepler, the whole plastic, philosophical and scientific importance of figures , specially in an environment as the latin tradition that has been for centuries fully focused on text.
no explicit 2d or 3d strucutre to laws beyond the table of contents
very interesting work has been done in recent times exploring how knowledge in figures (eg in euclid and arquimedes, or mathematical texts in china 2200 years ago) has moved acros time, one fun story that has appeared from recent research is that the edition of the greek text of euclid by Hibert in Leipzig in 1870 or so, the greek text everybody has used and still uses to look into euclid in greek, was based on about 6 greek manuscripts from the 9th century. It has been shown recently that Hibert completely modified the figures to present euclid in standard 19th century geomtircal style, and that in turn propagated the idea that euclid was doing 19th century geometry 2400 years ago, and that nothing had changed, which was more of an ideological porposition than a rendering of the facts
