Я не могу понять, как добавить кластеры маркера на эту карту. Он используется с Wordpress, так что пользователь может добавлять в него местоположения с панели инструментов Wordpress. Я довольно новичок в Google API, и у меня нет успеха с любыми примерами, которые я нахожу. Любая помощь приветствуется!Как добавить кластеры маркеров в свою карту Google?
