SVG 'Заголовок' стилизация всплывающей подсказки с несколькими заголовками

Question

У меня есть карта SVG США, в которой есть подсказка для каждого округа, отображающая название округа и его штат (см. Рисунок для уточнения)

Обратите внимание, что в каждом элементе «путь» есть элемент «заголовок».Элемент заголовка автоматически отображает всплывающую подсказку.

Как создать стиль для всех подсказок заголовка?Я в основном ищу стиль, который можно применить ко всем подсказкам
