json2dot

json2dot - A simple json to dot conversion tool

How does it work

Objects are turned into nodes. Where the node label contains all keys and values.

Every field with a nested object turns into a edge to that new object.

All JSON types except for arrays are supported.

Future changes

Move from node [shape=record] to HTML-like labels.

Support array type.
