        a       int
        b       int
Rows: 3
Data:
+---+---+
| a | b |
+---+---+
| 1 | 1 |
| 2 | 2 |
| 3 | 3 |
+---+---+
>>> g.export('output.json', orient='records')
>>> !cat output.json
[
{'a':1,'b':1},
{'a':2,'b':2},
{'a':3,'b':3},
]

If orient=”rows”, each row will be emitted as a JSON dictionary to each file line.

>>> g

        a       int

Data:
+---+---+
