问题
I'm unable to install pygraphviz even after installing graphviz and ensuring that cgraph.h is present in the directory.
I've also manually specified the directory for install. e.g. install-path
fatal error C1083: Cannot open include file: 'graphviz/cgraph.h': No such file or directory
Looking for any and all suggestions. Using Windows.

For those who visit this page, you may already come across to this fix or this issue on GitHub and try to install GraphViz2.38 manually. But neither of them will work since GraphViz and PyGraphViz are 2 different libraries
Mac or Ubuntu already have their solutions on GitHub, however for Win10 64-bit, it does not receive any fix yet since 2018. Installing pygraphviz on Windows 10 64-bit, Python 3.6
Someone have created a build of PyGraphviz 1.5 on his Anaconda channel for Windows 64 bit running Python 3.6, Python 3.7 or Python 3.8. If you're running Anaconda, you can install with:
conda install -c alubbock pygraphviz
