GraphVis | 可以应用于知识图谱可视化，复杂网络可视化分析，关系图可视化，网络拓扑图，布局算法，社区发现算法等应用场景。也可以作为 | Data Visualization library

I have been using this code for a long time now in a project. However, I have recently added llvm-config --cxxflags --libs to the compiler in order to link with llvm libraries and it started generating seg faults. I have located the error and it happens when I call base class's variables.

Here is a small example of what I a doing in Literals.hh

I'm trying to use Graphviz to generate a graph of a file system. The output should look something like this:

Circle shaped vertices are directories and square shaped vertices are files. Black colored edges represent the hierarchical relation between file system elements. Red colored edges represent a dependency relation from one file to another. Both types of edges are directed.

I have found examples on www.graphviz.org for creating hierarchical graphs, but they only include the hierarchical relation. Can this be implemented with Graphviz? If not, is there some other software I can use?
