i working on assignment, need generate graph of git repository arrows is there utility generate graph this? know gitg, gitk; need utility through can generate graph in same format 1 shown in picture? an answer inside se here . links alias , creating dot file based on git repository pretty add: [alias] graphviz = "!f() { echo 'digraph git {' ; git log --pretty='format: %h -> { %p }' \"$@\" | sed 's/[0-9a-f][0-9a-f]*/\"&\"/g' ; echo '}'; }; f" to .git/config. after this, can run , create diagram e.g. git graphviz head~100..head~60 | dotty /dev/stdin (also token link wiki resource). if redirect output dot-file, can manually compile graph on wishes dot or maybe neato. can adjust alias little better formatting (color, shape...) of e.g. nodes.
