Law goes 3D, takes get spicy
Show HN: Semantic atlas of 188 constitutions in 3D (30k articles, embeddings)
3D map of world constitutions drops — one commenter calls the whole thing a “liberal fantasy”
TLDR: A coder mapped 188 constitutions into a navigable 3D world of themes and topics, complete with smart search and comparisons. The loudest reaction: a takedown claiming documents don’t shape nations—culture does—sparking a debate over whether mapping legal words can ever capture real‑world power and behavior.
A new Show HN project turns 188 countries’ constitutions into a 3D map you can fly through, where each dot is a constitutional article and clusters show themes like rights, elections, and emergency powers. It’s nerdy, ambitious, and oddly mesmerizing: type a keyword or a concept, and the app highlights where those ideas live across the world’s legal texts. There are even stats that show how widely a constitution ranges across topics (called “coverage”) and how evenly it spreads (aka “entropy”).
But the top comment? A philosophical grenade. One user blasted constitutional worship as “a leftover of the liberal worldview,” arguing that no perfect document can save a society because culture always wins. In their words, the written layer is “a very leaky abstraction.” That single post set the tone: less “wow, 3D law space!” and more “can you really map power and people’s values like a star chart?”
Fans will see a bold new way to compare legal DNA across countries; skeptics see a pretty globe that might miss the messy real world where edits on paper don’t force change on the street. The vibe: a stunning demo colliding with a big, uncomfortable question — does mapping the words tell us anything about how we live?
Key Points
- •Each point in the 3D view represents a constitutional article or legal segment; proximity reflects semantic similarity, not country.
- •Country selection changes which constitutions are shown but does not alter the embedding’s global geometry.
- •Legal text is embedded into vectors and clustered into thematic neighborhoods; colors indicate political origin (country mode) or theme (cluster mode).
- •The platform supports keyword and semantic search, with results highlighted on the 3D canvas.
- •Country statistics include Coverage and Entropy; article details show Global Cluster IDs (with -1 for unassigned) and Probability for clustering confidence.
