Tree visualisation from taxonomy file

[kafka82]

I am have a file with a taxonomy built in it - using tax and parent_taxon IDs - however I am not quite sure how I can built a tree structure in Power BI so I can filter through the different items of the tree ? Ideally  I would like to use a decomposition tree but even if it was a simple matrix where I can filter down through the tree would be great -

What's the best way to do this in Power BI? Breakdown the table in different table and build a relationship ? Shall Import in a mySQL database and built the tree there ? How? Sorry for silly questions but am bit newbie to this!

I guess what I am asking is how to "unflatten" the file into a dataset I can filter in some sort of table or visual.

Here is the file with the taxonomy

Normally you would use the PATH functions for this.  However your sample data has holes.

Basically each parent MUST be present as a child as well.
