Two cosmologies are drawn through the same public data — one with a fixed cosmological constant, one where dark energy is allowed to drift. Nothing on this page is typed in by hand: every point, error bar and curve is fetched from the registry's data files at render time. Hover any mark for the measurement behind it.
viz_data.json is missing or unreadable — regenerate it with the extraction script, then reload. The engine draws nothing it cannot trace.
