How to create a Consort diagram in Qlik Sense

[Aviaf]

I'd like to create a consort diagram, used commonly for summaries of clinical trials.

It looks like this: https://www.ncbi.nlm.nih.gov/corecgi/tileshop/tileshop.fcgi?p=BOOKS&id=750543&s=60&r=2&c=2 

Is there an extension someone has used or any ideas?

There is a qlik extension for a Org Chart that may work here.

Here is an example with a family tree:

table:
load * inline [
id, label, parent_id
1, grandparent,
2, grandparent2,
3, parent, 1
4, parent2, 2
5, child, 3
6, child2, 3
]
;

Let me know if I can clarify anything.
