1$\begingroup$ I briefly closed this as a duplicate of physics.stackexchange.com/q/34561, but it seem that the earlier question is not very well defined as was closed. That said, this question currently has two distinct questions which goes against the functional model of Stack Exchange. Please ask one question at a time. $\endgroup$– dmckee --- ex-moderator kittenCommented Dec 15, 2012 at 21:20

Graphical explanations are most welcomed.
This is my personal favorite one of those (from MTW's "Gravitation").
For an animation, see, for example this Java applet.

For another excellent, and non-mathematical explanation on the cause of radiation see this EDN article: Understanding electromagnetic fields and antenna radiation takes (almost) no math
It breaks down different concepts rather nicely with plenty of graphics. It is, in fact, referenced from the Bible itself (not the holy one, but the one called Art of Electronics by Horowitz ...which itself is certainly sacred :D )
The article can also be downloaded as a PDF.
