One of the challenges of working with Git, or any source control for that matter, is managing branches. The GitHub network graph helps you visualize branches and how they fit together. I wrote a little command to open the webpage from your command line. Note: this only works on Mac, though it could easily be tweaked to work on linux.

Network graph

Put the following line in your .bashrc or .zshrc:

alias gn="git remote -v | grep 'git@github' | sed 's/origin.*:\([^.]*\).*/\1/' | head -n1 | read GH; /usr/bin/open -a \"/Applications/Google Chrome.app\" \"https://github.com/\$GH/network\""

Type gn from the root directory of your git project and it will open the GitHub network page inside of chrome.
