Specify the guaranteed minimal width (in pixels) of the rectangle, in which the annotation text is wrapped.
<p>
In diagram, annotations are typically displayed under the nodes depicting the respective components.
So, the width into which the annotation is wrapped is never smaller than the width of its component node.
However, some component nodes may be too small (narrow) to serve as a base for the annotation wrapping.

<div style="font-family: Dialog; font-size:12pt; border: double 3px #808080; padding: 3px; margin-top:12pt; margin-bottom:12pt">
The minimal width of the component node is determined by the parameter: <i>"DiagramKit | Layout | Nodes | Minimal Width"</i>
</div>

This parameter allows you to specify the minimal wrapping width, which will be applied in any case.
No annotation column will be narrower than this width.
<p>
Note that the value of this parameter will affect the total width of the diagram.
If you want the generated diagrams to fit into relatively narrow frame
(for instance, to print them on sheets of paper), you may need to reduce the value of this parameter.
