Required For Visual

sudo apt-get install graphviz

Install

go get github.com/tanmoyopenroot/go-dependency-graph

Command-Line

Simply execute main.go with one or more package names to visualize.

$ go run main.go const.go dot-graph.go generate-dependency-graph.go show-dependency-tree.go dot-template.go -show-std=true strings
Arguments:  [strings]

This generates a Graphviz's dot format file, to view execute the following:

$ dot -Tpng strings.dot -o strings.png
$ eog strings.png

-level and -show-std

Decide your dependency graph level and also choose whether to show standard library.
