memviz 
How would you rather debug a data structure?
| "Pretty" printed | Visual graph |
(*test.fib)(0xc04204a5a0)({
index: (int) 5,
prev: (*test.fib)(0xc04204a580)({
index: (int) 4,
prev: (*test.fib)(0xc04204a560)({
index: (int) 3,
prev: (*test.fib)(0xc04204a540)({
index: (int) 2,
prev: (*test.fib)(0xc04204a520)({
index: (int) 1,
prev: (*test.fib)(0xc04204a500)({
index: (int) 0,
prev: (*test.fib)(),
prevprev: (*test.fib)()
}),
prevprev: (*test.fib)()
}),
prevprev: (*test.fib)(0xc04204a500)({
index: (int) 0,
prev: (*test.fib)(),
prevprev: (*test.fib)()
})
}),

Usage
memviz takes a pointer to an arbitrary data structure and generates an easy to understand graph.
Simply pass in your data structure like so: memviz.Map(out, &data) and then pipe the output into graphviz.
For more complete examples see the tests in memviz_test.go.
Rendering with graphviz
Using the memviz output you can render the output directly as a png file (check out the implementation of at DataViz)
b := &bytes.Buffer{}
memviz.Map(foo, b)
dataviz_utils.WriteDotStringToPng(b.String(), "foo.png")
