The current release of Graphviz can be downloaded here: Downloadĭocumentation is available in the released package and from here: Documentation Discussions Graphviz has many useful features for concrete diagrams, such as options for colors, fonts, tabular node layouts, line styles, hyperlinks, and custom shapes. 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. It has important applications in networking, bioinformatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. Graphviz is open source graph visualization software. ![]() For example, for Latex output the images must be provided in Encapsulated PostScript (. eps, …) depending on which Doxygen ouput you’re willing to generate. You’ll need to have your images ready in several graphical formats (. Last thing that our sample project illustrates is inserting images into Doxygen documentation. After you have created your dia file you insert it into the Doxygen documentation using the Doxygen tag. On many Linux distributions come with a dia package. If you prefer drawing your diagrams directly instead of defining them as a plain text the Dia Diagram Editor can be a good fit for you. The definition of a PlantUML diagram in Doxygen must be enclosed in the and tags. You’ll need to download the jar file plantuml.jar and tell the jar location to Doxygen in your Doxyfile. To learn about the different PlantUML features you can refer to the great reference guide Drawing UML with PlantUML. PlantUML diagramsĪll kinds of UML diagrams can be created with PlantUML. In Doxygen, you can include a MSC diagram by using tag. The issue appeared with version 1.7.5, when Doxygen started treating Fortran modules as classes instead of the previously used, and more appropriate, namespace concept, with side effects including the absence of call/caller graphs. Similarly to DOT graphs, the parts of the mscgen diagrams can be made clickable, too. On many Linux distributions you can find it in the mscgen package. Mscgen is a handy utility for generating sequence diagrams. On most distributions the dot utility can be found in the graphviz package. In order to generate the DOT diagrams you need to have dot utility installed. Doxygen itself uses DOT graphs to generate the class inheritance and call graph diagrams. The nodes of the graph can be made hyperlinks as it is demonstrated in the sample project. Doxygen tag allows for embedding the DOT graph definition directly into your documentation. You can find a great documentation with many examples of DOT graphs in the manual Drawing graphs with dot. The DOT language allows for simple definition of graphs. However, it can include diagrams and images generated by external tools. You can check out the project source code and the generated HTML and PDF output at:ĭoxygen on its own doesn’t implement graphical operations. In order to show the graphical capabilities of Doxygen I created a sample project. In the last article of the Doxygen miniseries we’ll go over a couple of options how to include diagrams and images in Doxygen documentation. Is your technical documentation hard to read? Diagrams and images liven up technical documentation and help the reader to better understand the subject. ![]()
