Lag when loading my large phylogeny in radical mode in observable

[xieduo7]

There is some lag when I use my phylogenetic tree in observable by using the sample code and replacing the original tree with my tree. When scrolling the slider, it is slow to respond. Maybe this is because my phylogeny contains too many tips? How can I improve it? Is this caused by the observable? Maybe I can use an independent javascript instead of the observable?

Best,
