Update data path handling and remove unused example assets

- Modified the `create_data` function to accept a more general data path, enhancing flexibility in data loading.
- Updated the data variable to point to the new examples directory.
- Removed unused image assets (cover.png, favicon.ico, SavtaDepth.png) from the examples directory to clean up the project.

These changes streamline data management and reduce clutter in the project structure.
