How can I display Newick tree at taxonomic level

Hi @Eman,
The short answer is you currently can’t do that within Qiime2 itself. But see this post with an example of how to do this outside using an interactive tree building tool like iTOL.
That being said, if you have your tree, taxonomy and table you should already be able to do this within R if you are using something like phyloseq which accepts taxonomy files and can use those as tree tip names.
