<p>There's overlap, of course.  I mean to cast no aspersions on our graphic design site--I wasn't even aware of its existence and I'm sure its users are wise and experienced--but in general I would actively avoid advice from graphic designers concerning the design of statistical graphics unless they had statistical credentials as well.  And even then I would be cautious.</p>

<p>(My favorite example of how far wrong you can go is Bounford's <a href="http://rads.stackoverflow.com/amzn/click/0823015726" rel="nofollow noreferrer">Digital Diagrams</a> book.  Written by a well-established graphic designer and promoting itself as "effective design and presentation of statistical information," this book consistently provides hundreds of examples of everything Cleveland, Tufte, Wainer, <em>et al.</em> have shown to be truly awful approaches: an atlas of chartjunk and other distracting embellishments of all kinds guaranteed to obscure and warp any information that might have been present in the data.)</p>

<p>Thus, when questions come along even about seemingly trivial elements of the design of statistical (or scientific) visualizations, I believe they are very much on topic here.</p>
