A colour in a dataset is usually an assertion nobody can check. These can be: each axis publishes its ramp stops, its interpolation and the domain the values were stretched onto, so any hex value in the graph can be recomputed from the graph alone. Watch lado:domainBasis — an observed domain is read off this corpus, which means adding a findspot can change the colour of one that did not change at all. The chronological axis avoids red-green on purpose: late material is not worse material.

The graph is fetched as a static file and queried in your browser with
rdflib under Pyodide — there is no endpoint, and nothing you type
leaves your machine.
