For a simple, single-planet system viewed edge-on, what shape does the velocity curve plot trace over time?

Answer

A sinusoid (or sine wave)

When the measured radial velocity is plotted against time, the resulting curve for a simple, single-planet system traces out a periodic, wave-like function, specifically a sinusoid.
