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.

2026-10-25 [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)
