Well, maybe it actually is easier than I thought to bundle everything into a single html file (I thought you couldn't embed fonts into html, but apparently you can [1]).

Anyways, in case of this application, all visualizations together are like 20MB (the monaco editor is a significant part of it). Having them split up and only loading things one demand significantly increases startup time.

Also, base64-encoding all the binary resources is a little bit inefficient.
