Graphviz calculates flexible graphs

Conclusion

Graphviz offers a lot of potential to fulfill tasks with just its automatic functions. The program has a lot to offer in terms of formatting boxes and arrows. Note, however, that Graphviz does not provide ways to define your own styles; therefore, some standard graph types cannot be properly rendered.

Additionally, labeling is with text only, and use of other elements, such as math formulas or images, is not supported. The additional Dot2tex [7] tool can provide some help in positioning objects and converting the output to the corresponding LaTeX format. l
