Graphviz
Graphviz is an open source graph visualization software. The Graphviz layout programs take descriptions of graphs in a simple text language, and make diagrams in useful formats, such as images and SVG for web pages; PDF or Postscript for inclusion in other documents; or display in an interactive graph browser.
Our HSE Release Automation Tools use Graphviz for rendering PlantUML textual descriptions into diagram image files.
