Definition
Let $f$ be an iterated rational function defined on the extended complex plane $\overline \C$.
The filled Julia set of $f$ is the set of those points in $\overline \C$ whose orbits under $f$ are bounded.
Examples
Julia Set for $-0.13 + 0.75 i$
The below is a graphical representation of the Julia set for the rational function $z \mapsto z^2 + c$ for the point $c = -0.13 + 0.75i$:
