% Demonstrates class member visibility, including the protected marker "#".

% The diagram body is read verbatim, so write PlantUML exactly as in a .puml
% file -- including characters LaTeX treats specially, such as "#". Write them
% as-is; do NOT escape them (e.g. use "#balance", not "\#balance"). See #24.
%
% LaTeX/TikZ output (PlantUML's -tlatex). Note: PlantUML invokes xelatex
% internally to measure text for TikZ output; see also example-class-visibility
% in --png and --svg variants, which do not need xelatex.
