    dpi=360;
    node [shape=box];
        "github.com/gofiber/fiber/v2" -> "github.com/valyala/fasthttp";
        "github.com/valyala/fasthttp" -> "github.com/andybalholm/brotli";

        "github.com/valyala/fasthttp/reuseport" -> "github.com/valyala/tcplisten";

You can view a output graph with tool https://dreampuf.github.io/GraphvizOnline or http://viz-js.com

If you have the graphviz tools installed you can render it by piping the output to dot:

$ godepviz github.com/gofiber/fiber/v2 | dot -Tpng -o godep.png

Export SVG file with a large graph have many nodes of dependencies

$ godepviz github.com/gofiber/fiber/v2 | dot -Gdpi=0 -T svg -o godep.svg

Run from source code

$ go run main.go go.uber.org/zap | dot -Tpng -o godep.png
