PyVista-like API for vtk.js - Bring intuitive 3D visualization to the browser.

## Vision

Provide a familiar PyVista interface that works seamlessly in browser environments (Pyodide, stlite, JupyterLite) by leveraging vtk.js under the hood.

## Quick Example (Goal)

```python
import pyvista_js as pv
import streamlit as st

# Create a plotter
plotter = pv.Plotter()

# Add a mesh
mesh = pv.Sphere()
plotter.add_mesh(mesh, color='red', opacity=0.8)

# Display in browser
plotter.show()
```

## Features (Planned)

- 🎨 **PyVista-like API** - Familiar interface for PyVista users
- 🌐 **Browser-native** - Runs entirely in the browser via Pyodide
- ⚡ **vtk.js powered** - Leverages the power of vtk.js for rendering
- 📊 **Streamlit/stlite support** - Easy integration with web frameworks
- 🔧 **Lightweight** - No server required, pure client-side

## Installation (Future)

```bash
pip install pyvista-js
```

For Streamlit support:
```bash
pip install pyvista-js[streamlit]
```

For Pyodide/stlite:
```python
import micropip
await micropip.install('pyvista-js')
```

## Usage

### Basic Example

```python
import pyvista_js as pv

# Create a plotter
plotter = pv.Plotter()

# Add a mesh
mesh = pv.Sphere(radius=1.0)
plotter.add_mesh(mesh, color='red', opacity=0.8)

# Display (in Pyodide/browser environment)
plotter.show()
```

### Streamlit/stlite Example

```python
import streamlit as st
import pyvista_js as pv

st.title("3D Visualization")

# Create visualization
plotter = pv.Plotter()
sphere = pv.Sphere()
plotter.add_mesh(sphere, color='blue')

# Display in Streamlit
pv.pyvista_chart(plotter, height=600)
```

## API Design

### Core Classes

```python
# Plotter - Main visualization interface
plotter = pv.Plotter()
plotter.add_mesh(mesh, **kwargs)
plotter.show()

# Geometric objects
sphere = pv.Sphere(radius=1.0, center=(0, 0, 0))
cube = pv.Cube()
cylinder = pv.Cylinder()

# Mesh operations
mesh.points  # NumPy array of vertices
mesh.faces   # Cell connectivity
```
