Graph Visualization Software includes several layout programs that 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.
Graphviz also supports GXL, an XML dialect.
