The sources are categorized by textual domains such as code, government and legal documents, wikis, web content, academic papers, online forums, public domain texts, and educational resources. Each bar represents a different source, with the dataset size indicated on a logarithmic scale ranging from 1 MB to 1 TB. Notable sources include Stack Exchange at approximately 275 GB, PubMed Central at around 306 GB, Wikipedia at about 89 GB, ArXiv at roughly 400 GB, and various other domains contributing smaller proportions to the total size.
