Every Surface

Internal index of the World Languages estate and its satellites. Everything linked here returned 200 on 2026‑10‑06.

Served straight from ~/html/datavis/language (repo lukeslp/inner-dialogue) with no build step, so an edit there is live.

Front of house linked from the index

• / World Languages Six tiles. The only public doorway; every poster below is reachable only by URL or from a sibling's help dialog. indexed
• /kinship/ Inner Dialogue Interactive globe of 8,618 languages: sister chords through the interior, speaker weight across 421 families. indexed
• /circle/ Crossings The globe's edge set laid flat. Rim ordered by geography, so a chord over the middle is a family split across the world. indexed
• /network/ Entanglement The whole classification in one space, left to resolve itself under live physics. 421 families sharing no edges, still interwoven. indexed
• /tree/ Interactive Radial Tree 7,370 languages, themed, expand/collapse, speaker flow. indexed

One word at a time 12 · word graphs

Contact histories rather than family trees, drawn by shared/wordgraph.js with typed edges (borrow / inherit / coin / shift / blocked); banner and foot from shared/sheet.js. Adding another needs only a data file.

Atlases 2 · Vite SPAs, four hosts

Not in this repo. Built from ~/projects/orthography and ~/projects/sign-language-atlas, mounted by the writing_spa / sign_spa Caddy snippets on datapoems.io, lukesteuber.com, world‑languages.com and diachronica.com. Their deploy timers refuse a dirty tree.

• /writing/ Tree of Writing The orthography atlas. An index tile, so it is the one poster-adjacent surface with a public doorway. indexed
• /sign/ Sign-Language Atlas Marker shape is primary community context: circle Deaf-community, diamond village/shared, triangle school-emergent, square alternate. noindex

Elsewhere other hosts

• diachronica.com/etymology Diachronica Etymology Visualizer Flask/gunicorn on :5013 (etymology.service). Source at ~/kernel/servers/diachronica/etymology; bulk data in etymology_atlas/parquet. other host
• diachronica.com/dev/wals-map/ WALS feature map One typological parameter at a time as coloured dots. /wals-map/ 301s here. other host
• datapoems.io/datavis/syntax/ Syntax trees An index tile here, via ?theme=midnight. other host
• datapoems.io/datavis/poems/language/ The older language set pie · constellation · tree-3d · network, plus print variants. Not under version control and served live, so back up to ~/backups/ before editing. other host

Diachronica /dev/ 18 · other host

The sibling estate on diachronica.com, all noindex and served from ~/www/diachronica.com. That webroot is build output: the sources are static/ in the diachronica server repo and the release builder namespaces every path under /dev/, so edit the source, not the copy. Legacy top-level paths (/tree, /evolution, /network…) 301 in here.

• /dev/ Diachronica Staging mirror of the landing page, a different convention from this index. Links the six app surfaces below. hub
• /dev/visualizations/ Visualizations The viz hub: constellation, explorer, pie, language/evolution, network, tree. hub
• /dev/language/evolution/ Language Evolution Visualizations Gallery for the five D3 views below. Data is language_evolution.json beside it. gallery
• …/viz1_phylogenetic_tree.html Phylogenetic Tree d3
• …/viz2_force_network.html Force Network d3
• …/viz3_timeline.html Timeline d3
• …/viz4_geographic_map.html Geographic Map Also pulls d3-geo-projection and topojson. d3
• …/viz5_sunburst.html Sunburst d3
• /dev/explorer/ Language History Explorer Has three sub-views: pie/ (Proto-Indo-European family), force/ (constellation), tree/ (world families). app
• /dev/tree/ World Language Families viz
• /dev/constellation/ Language Constellations viz
• /dev/network/ Network Titled for dr.eamer.dev, predating the move. viz
• /dev/sky/ The Night Sky viz
• /dev/evolution/ How Words Change Timeline-led. Distinct from the five-viz gallery above, despite the name. viz

• /dev/concordance/ Concordance app
• /dev/language/ Language Section index over evolution/ and the history data. hub

Print vector PDFs

Every poster set on a real sheet with bleed and embedded fonts, by scripts/poster-print.mjs. Sizes and the reasoning are in docs/printing.md.

• /dev/print/ Print Files One row per poster and banner: trim, smallest type at that trim, PDF and font-inlined SVG. Built from the manifest the print script writes, so it lists exactly what is on disk. noindex

Stubs, legacy, unrouted

• /tongues/ Descent of Tongues Renamed. Meta-refresh pointer to /cognates/; the destination is what GoatCounter counts. redirect stub
• /karaoke/v2/ Empty Orchestra, v2 The wordgraph rebuild. /karaoke/ still serves the original journey.js, deliberately left alone so a shipped page was not silently restyled. unlinked
• /radial-tree-interactive.html Radial tree, old filename Redirect stub kept from before the tree moved to /tree/. legacy
• /radial-tree-speakers.html Radial tree, speaker weight Standalone variant, still served, linked from nothing. legacy
• etymology/{evolution,tree}/ Etymology sub-visualisations: stale source copies These directories under ~/kernel/servers/diachronica/etymology are superseded, not missing. The live equivalents are published under Diachronica /dev/ below; etymology/tree/index.html is a byte-identical copy of its own circle.html and differs from what is served. Do not route them. superseded
• /areal/ Neighbours Retired and deleted 2026-08-20 (commit 30955c7). The 404 is correct and unreachable; source is in git history. Do not restore. deleted
