Json Representation of AD Computation Graph
###########################################

Syntax
******

| *json* = *f*\ ``.to_json`` ()
| *f*\ ``.from_json(json`` )

f
*
This is a :ref:`d_fun<py_fun_ctor@Syntax@d_fun>` function object.

json
****
is a ``str`` containing
a Json representation of the computation graph corresponding to
*f* ; see the CppAD documentation for
`json_ad_graph <https://coin-or.github.io/CppAD/doc/json_ad_graph.htm>`_.

to_json
*******
In this case, the function object *f* is constant and
the return value *json* is created.

from_json
*********
In this case, the argument *json* is constant and
the function *f* is changed so it corresponds to *json* .
