- Статья "Графвиз" заслуживает того,чтобы через неё пролегла структурирующая цепочка,к которой можно будет привязать многие статьи Летописи.--Эдуард Гольянов (обсуждение) 17:03, 2 января 2016 (MSK)
Graphviz is an open-source, cross-platform graph drawing toolkit and can be found at http://www.graphviz.org/ Graphviz is open source graph visualization software. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. It has important applications in networking, bioinformatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains.
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. Graphviz has many useful features for concrete diagrams, such as options for colors, fonts, tabular node layouts, line styles, hyperlinks, and custom shapes.
Graphviz has its own language, named DOT, which is simple, elegant, and powerful. The good thing about Graphviz is that you can write its code using a simple plain text editor. A wonderful side effect of this feature is that you can easily develop scripts that generate Graphviz code! Also, most programming languages, including Python, Ruby, C++, and Perl, provide their own interface for creating Graphviz files using native code.
