Nice api! Thanks for the link!

About the js, don't get me wrong, the site looks gorgeous as it is (with the js)!

It's just for no-script users, the idea of having it rendering a simple nojs if the js can't be loaded is always nice. But take that as niche feedback.

About having it inside the SVG, well that is the only thing I miss from the old versions. It was a really nice way to visualize, specially offline. But I understand that the tree with the filters is far superior, and I thank you for that ;) .
