@lexszero Вот что опытные графвизарды пиздят: As a side note: While graphviz is great for generating graphs for large datasets, it is less awesome for creating things like ER diagrams, flow-chars and sequence diagrams. It's possible and relatively straight forward, but the amount of time you have to put down to make something come out right is often unjustified because you could achieve the same thing with a Wsywig-GUI modeling tool in a fraction of the time. However, the time you spend doing that will help you towards learning the syntax and properties of the language which really comes in handy when you need to visualize some large or complex problem (where GUI modeling tools would be useless).
