### Describe something you’ve made

Hi everyone!

I’m excited to share [pyvista-js](https://github.com/tkoyama010/pyvista-js), a new library that brings the intuitive API of [PyVista](https://github.com/pyvista/pyvista) to the browser via [vtk.js](https://github.com/Kitware/vtk-js).

It is specifically designed to work seamlessly in WASM environments like stlite and JupyterLite, making complex 3D visualization accessible without a dedicated backend server.

**Why pyvista-js?**  
While PyVista is powerful, rendering interactive 3D graphics in a purely client-side environment (like stlite) has been a challenge. pyvista-js bridges this gap by providing a familiar Pythonic API that feels like PyVista but runs entirely on vtk.js.

Neat !

Why not leverage VTK.wasm instead of VTK.js ?

Awesome idea! I created [pyvista-wasm](https://github.com/tkoyama010/pyvista-wasm) . It works fine 😉
