Usage

memviz takes a pointer to an arbitrary data structure and generates output that can be used to generate an easy to understand diagram using graphviz.

To generate a diagram, first you will need to install graphviz on your system following the instructions here.

Next, use memviz.Map(out, &data) to generate a graphviz dot file and then pipe the output into graphviz.

For examples of how to use memviz, see the code sample in the example folder and the tests in memviz_test.go.
