Title: The denominator matters
Meaning: 340 threatened species among 774 with sufficient data; 118 additional species lack enough evidence.
Limits: Relative extinction risk, not reef area lost. Historical assessment data end in 2020; the 2023–2025 bleaching event came later.
Data: [{"label":"Species with sufficient data","unit":"species","max":774,"rows":[{"label":"Threatened","value":340,"display":"340 · 44%","tone":"accent"},{"label":"Other assessed categories","value":434,"display":"434 · 56%","tone":"muted"}]}]
The native responsive figure preserves these numbers, units and limitations. The SVG is a standalone export.
