Las cuatro barras grises de la derecha valen lo mismo (660 urgencias): cuanto más corta, más recorrido tiene el panel.",
      "alt": "Cuatro paneles con el mismo eje de tiempo. Arriba, las urgencias mensuales: cada enero sobresale y cada octubre se hunde, con la tendencia superpuesta en línea discontinua. Debajo, la tendencia sube de 4.031 a 4.600 urgencias al mes sin un retroceso. El tercer panel repite el mismo perfil anual —enero +766, octubre −395— y el cuarto sólo tiene dos meses que sobresalgan en cuatro años: julio de 2022 y enero de 2024."
