overflowing integers cause IDs to be incorrect (and leads to wrong representation)

[Styx13]

Hello,

I just had a case where I am trying to create a graph and noticed its representation was wrong given the list of nodes and edges given as inputs.

The reason turns out to be that my nodes used very long numbers as ID (int64 that were stored as strings in a database).

In my case I am using Python (Jupyter notebook), and I doubled checked that the IDs I use when I build my node list are actually stored as strings in Python.

However, it is probably the javascript code generated by Brunel that tries to convert those strings into integers (because in my case my IDs are only numbers).
JavaScript does not support 64 bits integers and thus the IDs were no longer correct, leading to wrong data representation.

A workaround in my case was just to prefix all my ID with "id_" which would prevent Javascript from trying to convert my strings IDs into integers.
