% A mindmap rendered as latex/TikZ (the default). Diagram types other than the
% default UML need their own @start.../@end... markers, so they are kept here.
%
% The package renders the TikZ text sans-serif by default (\PlantUmlTikzFont) so
% it matches the font PlantUML used to size the boxes; otherwise the document's
% serif font leaves uneven margins inside the boxes (#14). To use a different
% font, \renewcommand\PlantUmlTikzFont (e.g. \rmfamily), or render as png/svg.
