Supported selectable economies: Argentina (ARG), Bolivia (BOL), Brazil (BRA), Chile (CHL), Colombia (COL), Costa Rica (CRI), Dominican Republic (DOM), Ecuador (ECU), Guatemala (GTM), Mexico (MEX), Panama (PAN), Peru (PER), Paraguay (PRY), Uruguay (URY) and El Salvador (SLV).

When loading live records, the tool requests the selected indicator for all selectable economies over 1998–2025 and filters the visible panel by the user's study window. It does not label missing years as zero and never extrapolates beyond reported observations.

Source labeling: synthetic-demo, worldbank or imported; source labels in exported JSON are descriptive, not cryptographic attestations.
