Hello, VTK Team,

To decorate the README of the [vtk-docs-l10n](https://github.com/localizethedocs/vtk-docs-l10n) project, I would like to place the VTK logo at the top. And I have found the VTK logo in SVG format:

- [File:Visualization Toolkit logo.svg - Wikimedia Commons](https://commons.wikimedia.org/wiki/File:Visualization_Toolkit_logo.svg)

However, I would like to confirm what the **license** of this logo and what **attribution** is required.

The logo is part of the VTK toolkit and should follow the same [BSD 3-clause license](https://gitlab.kitware.com/vtk/vtk/-/blob/5e26033e83257007465f0108408f3663da3188e2/Copyright.txt) as the toolkit.

Hello @sankhesh,

Thanks for the information. If so, how about the following attribution?
