The spacing parameters of radial layout
modes are controlled by the same CSS statements and methods as
used for free and level layout modes.
void setParentChildOffset(float offset);
void setSiblingOffset(float offset);
void setBranchOffset(float offset);
The sibling and branch offsets are minimum
distances tangential to the circles or ellipses, while the
parent-child offset is a minimum distance radial to the circles or
ellipses.
The following figure shows the spacing
parameters in radial layout mode.
