Pangenome presence absence viz ?

[colindaven]

Dear devs,

I'm interested in visualizing a pangenome matrix from odgi pavs in JBrowse1.

Maybe someone has made something like this viewer, panache as an example.

I think it might be possible using a bedgraph -> bigwig conversion, and then individual customized tracks with low track height, eg 50px. But could something more elegant be done ?

For example the below matrix would be represented by 3 separate bedgraphs/bigwigs, each containing the binary presence absence data in the last 3 columns.

Input format tsv input example (more at https://odgi.readthedocs.io/en/latest/rst/tutorials/presence_absence_variants.html )

chr1  10000 20000 1 0 0
chr1  20000 30000 0 1 0

Thanks, Colin
