Each buzzword’s trajectory by year — how many papers use it and how much those papers are cited. Compare one, a few, or the whole field. Citations note: Semantic Scholar reports a paper’s current total, so “citations” here means the citations earned by papers published that year (cohort impact), not year-by-year accrual.
Every buzzword’s curve at once, coloured by the Colour lens. Click a group’s eye to hide/show it, or Show all / Hide all. Hover a line to pick it out. Normalise rescales each line to its own peak so you compare shape, not size.
Per year, stacked by group — the changing composition of safety research. Size switches papers ↔ citations; Colour switches the grouping (glossary themes, MIT risk domains, semantic clusters, or co-occurrence communities).
