Hi! I'm Niels from the community science team at Hugging Face. I noticed this dataset card could be improved with additional metadata and links to the associated research.
This PR:
- Adds a link to the [accompanying paper](https://huggingface.co/papers/2605.15511).
- Adds a link to the [official GitHub repository](https://github.com/geometric-intelligence/ogbench).
- Updates the `task_categories` to include `graph-ml`.
- Adds a sample usage section with instructions on how to download the datasets and train models using the provided framework.
