2 years ago I am not sure if this is about this library here (or rather about xgdboost?).

You seem to be in the wrong place (maybe you mean https://github.com/dmlc/xgboost/issues?), closing.

I find graphviz can viz the tree. however, it is only node and leaf. when I use Booster.get_dump(fmap='',dump_format='text',with_stats=True) I can get the gain&cover. how can I viz the gain&cover on trees?
