[BenKaehler]

Dependencies: #1, #2

Prerequisites:

1. Python programming.
2. Javascript programming and HTML.
3. Understanding of QIIME 2 visualisations.
4. Understanding of igraph output format.

Write a Python script to create the visualisation that takes the Network semantic type and maybe the original table as inputs and displays an interactive network. It would be great if we could produce an interactive display of the network using the d3 javascript library.
