From what I've heard, manuscripts are strictly text with no fancy fonts or artwork etc. What about the use of diagrams, charts or text/info in that kind of sectioned off, image-based style? The best example I can think of is Jurassic Park and the Lost World; in both of which Michael Crichton extensively uses diagrams, charts and snippets from computer screens to show information and give the book more of a sciency feel. Not to mention the iterations at the start of each chapter with the use of dragon curves. Would he have submitted all this in a manuscript to his editor/an editor, and is that possible for somebody who's not yet published on anything? I want to do a similar thing, with the use of visual snippets from computer screens and what not to show information or text. Have any of you done this?
