Contributions summary:Francois primarily contributed to the `fury` library, focusing on improvements to how it handles data for visualization. They modified the `numpy_to_vtk_cells` function in `fury/utils.py` to support different data types and handle empty arrays. This included adapting the code to correctly cast and use `offsets_dtype` and `ArraySequence` objects. These changes suggest an effort to improve the flexibility and robustness of the library's core functionality.
