Basically, I want to move a graphic (such as a circle) along a given path (such as sin(x)). I was thinking that the trick might be making the x and y coordinates of the circle vary based on the equation, but I have not been able to make anything except a circle that just sits there.

You need to specify the PlotRange:
f[x_] := Sin[x];
Manipulate[Graphics[{Circle[{x, f[x]}, 0.5]}, PlotRange -> {{0, 5}, {-2, 2}}], {x, 0, 5}]

$\begingroup$ Thank you, the missing PlotRange was exactly my issue. Thanks so much for the speedy response! $\endgroup$– kneu93Commented Jan 3, 2013 at 12:44

ManipulateandCircleandGraphics. Also, the demonstrations site is bound to yield some relevant code... $\endgroup$PlotRangecan help them in similar situations. $\endgroup$
