_scripts/make_graph.py

#!/usr/bin/env python3
"""Generate a self-contained interactive graph of the discourse (D3 force layout).

Nodes are ideas (blue) and the papers engaging them (amber); edges are typed
stances, colored so positive/negative influence is legible — solid green
argues-for, solid red argues-against, gold-dashed nuances, grey-dotted tests.
Output is ONE HTML file (D3 loaded from CDN), interactive: drag, scroll-zoom,
hover a paper for its title. This exists because building it by hand is fiddly
(edge typing, dashed legend, force params) — parameterize instead of re-deriving.

    # a few explicit ideas
    python3 _scripts/make_graph.py replay-is-necessary-for-class-IL \
        protecting-important-weights-prevents-forgetting --out reports/debate-graph.html

    # every contested idea + the papers on each side
    python3 _scripts/make_graph.py --contested --out reports/contested.html

    # one idea's whole neighbourhood
    python3 _scripts/make_graph.py --idea generative-replay-can-substitute-stored-data

Flags:
    --contested        use all ideas with `status: contested`
    --idea SLUG        shorthand for a single idea (same as passing it positionally)
    --embed            strip the page header (for embedding in an <iframe>)
    --title TEXT       header title (standalone only)
    --out PATH         output file (default reports/graph.html)

To publish into the HF Space, see skills/visualize-graph/SKILL.md — `hf upload`
tries to create-a-gradio-repo and 402s on a free static Space; use the Python
API `HfApi().upload_file(...)` instead.
