Please re-open.
I just built the latest superset from scratch following CONTRIBUTING.md and this bug appeared.
I have done some investigating and found the culprit. Within _superset/viz.py_ the method `json_dumps` of class `BaseViz` calls `json.dumps` with the keyword argument `ignore_nan`. It should resolve to the **simplejson** package which accepts that keyword argument. Only `json.dumps` points to the builtin **json** library not **simplejson**.
Removing the alias for **simplejson** rectifies the problem.
I'm having a hard time understanding why the error occurs at all??
