i have generated some results through HumanN and now i'm trying to visualise it using GraPhlAn.
graphlan_annotate.py --annot 04b-hit-keg-mpt-cop-nul-nve-nve-graphlan_rings.txt 04b-hit-keg-mpt-cop-nul-nve-nve-graphlan_tree.txt output.xml
i'm running above command and it's running correctly and i'm getting output.xml.
graphlan.py output.xml image.png --dpi 150 --size 7
while running this, i'm getting error
