I am a newbee for graphviz, what I want to do is generate a picture that accept a json which describes a graph, I want to call the api in my application, and I want to use cpp as my language.
I read the document but
https://www.graphviz.org/documentation/ but just found some easy and simple case
## Sample Programs using Graphviz * [demo.c](https://www.graphviz.org/dot.demo/demo.c) * [dot.c](https://www.graphviz.org/dot.demo/dot.c) * [example.c](https://www.graphviz.org/dot.demo/example.c) * [simple.c](https://www.graphviz.org/dot.demo/simple.c) * [Makefile](https://www.graphviz.org/dot.demo/Makefile)
I know how to do it using the command line tool, but I am confused about how do do it in the program.
Is there any cpp lib?
