I ran the code from the README.md and I get this output:

The \n newlines are not interpeted and it's difficult to see the structure of the output. This is the case when using python3 but not python2.7.

We probably need to tweak the readme.

The code should say: print(g.serialize(format='json-ld', indent=4).decode())

The default serialization is bytes, not UTF8

Oops - managed to accidentally push the proposed change into the 1.1 branch w/o a pull request. Apologies...

raghav17083 commented 4 years ago

Is this issue still open? As in, do we have to use .decode() after calling .serialize() on a graph?
