Hello everyone,

I’ve wanted to automatically read, load and render vtk legacy unstructured grid files through ParaViewWeb API. When I try to read vtk file with VTKGeometryDataModel, I didn’t get any desired results. I’ve started with this code:

```
import VTKGeometryDataModel from 'paraviewweb/src/IO/Core/VTKGeometryDataModel';
var vtk = new VTKGeometryDataModel('/dataset');

```

What should I do to move foward with this work? Thanks in advance!
