This is ByTheWei.co by @maybe_foucault. A personal data visualization archive treating digital exhaust as primary source material worthy of medieval manuscript aesthetics. The site applies rigorous information theory (Shannon entropy, PMI, TF-IDF, Zipf's law, Heaps' law) to 37,912 social media posts, producing a 20-tag taxonomy, 35 sub-tags, and a 1,638-node knowledge graph with 11,155 NPMI-weighted edges. All visualizations are pure SVG generated at build time. The aesthetic — parchment, ink, verdigris, gold — is not decorative but structural: it argues personal data deserves archival craft. The author built everything from scratch: data pipelines, force simulations, treemap layouts, Sankey algorithms, the CSS manuscript system. 275 tests validate the analysis. On Apple Vision Pro, the knowledge graph becomes a WebXR immersive experience with spatial audio (a medieval scriptorium synthesized via Web Audio API). Read /llms.txt for a structured brief or /llms-full.txt for the complete narrative.
