2026-11-03 [entries] Add the date when each entry was added, and remove icon_hash by Tiago de Paula Peixoto beff7c9

The dates are those of the commits that first added the entries' files
(2020-08-11 for the entries of the initial commit); renamed entries keep
the date of their first name.

2026-11-03 [entries] Prefix the properties in the descriptions with (Node), (Edge) or (Graph) by Tiago de Paula Peixoto bc3dbbd

The lists of properties at the end of the descriptions marked edge
properties with "Edge" but left node properties unmarked, or grouped
them in "Nodes: `a`, ...; `b`, ..." items, so the kind of a property
was often unclear. Every item now starts with (Node), (Edge) or (Graph),
followed by the property names, a colon and the explanation, one item
per property or group of properties; qualifications (kinds of nodes,
networks) follow the names in parentheses. Properties that were only
named got a short explanation, and a few items that named the wrong
kind of property were corrected.

2026-11-02 [entries] Remove unneeded code from the entries by Tiago de Paula Peixoto 2c69f19

Unneeded "global files" statements, unused imports and variables,
f-strings without placeholders, duplicate keys in foodweb_little_rock
(keeping the order and the values used), and the second definition of
get_lines() in twitter_higgs. Nothing changes in the networks or
descriptions.

2026-10-26 [entries] Use American spelling in the descriptions by Tiago de Paula Peixoto 802d564

British spellings in the titles and descriptions of 69 entries (e.g.
labelled, organisation, millimetres, centres, anonymised, neighbours,
analysed, modelled, colour, licence) are replaced by the American ones.
Proper names keep their spelling (Otago Harbour, the Centre for Water
Systems, the Centre jeunesse de Montréal, the Dutch Ministry of Defence),
as do quoted upstream terms, citations, and property names.

2026-10-25 [entries] Lay out spatial networks with cfd_layout() without the SBM partition by Tiago de Paula Peixoto 9db8d77

Road, power grid, public transport, water and river networks and physical
meshes override get_pos() with the default parameters of cfd_layout(),
without grouping by the partition of the SBM fit.

2026-10-25 [entries] Move KONECT-derived entries to their original sources by Tiago de Paula Peixoto 45943ea

The entries now download the data from where KONECT obtained them (live
or via the Wayback Machine), gaining the metadata KONECT dropped (names,
identifiers, timestamps, attributes), with descriptions and citations
rewritten from the original sources:

- Ma'ayan lab collection: faa_routes, foodweb_little_rock (taxon names
  were assigned to the wrong nodes), interactome_pdz, interactome_figeys,
  interactome_stelzl, interactome_vidal
- Pajek collection and primary sources: word_assoc (from the Edinburgh
  Associative Thesaurus; KONECT dropped all counts >= 10), foldoc,
  new_guinea_tribes
- bitriad: elite, ceo_club (adds the CEO KONECT's copy lacked)
- Lovro Subelj: cora, euroroad (adds isolated cities and parallel roads)
- SNAP: elec (all votes, with elections and nominators)
- Zenodo: wiki_talk (user ids and roles)
- MPI-SWS: flickr_growth, facebook_wall (edges now point from poster to
  wall owner, as documented), wikipedia_growth (full timestamps)
- Other sources: prosper, jester, reactome (the 2014
  release KONECT used), unicodelang (CLDR 27), wordnet (WordNet 3.1),
  chicago_road (TNTP ChicagoRegional)
