% 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). To measure text for TikZ, PlantUML
% auto-detects an installed LaTeX engine (lualatex, xelatex, or pdflatex), so no
% specific engine is required; see also the --png and --svg variants, which need
% no LaTeX engine at all.
