Importing VTK.js as an external script

This guide illustrates how to build a VTK.js application by leveraging import maps. While this approach may require a modern browser that supports import maps, it offers a cleaner setup and gives you fine-grained control over which modules are imported.

Below you can find an HTML file example that demonstrates how to use VTK.js with import maps to create a visualization.
