PlantUML - Text to Diagram

Recentemente, descobri essa ferramenta versátil para criar diagramas a partir de textos estruturados.

Vejo como grande vantagem que é possível armazenar os diagramas em repositórios, acompanhando histórico de altera??es de maneira eficiente e clara, além de ocupar menos espa?o de armazenamento.
