Необходимо при наведении курсора на определенный штат, окрасить его и вывести подсказку с информацией об этом штате.

P.S Карта неполная, всего несколько штатов, так как есть ограничение - не больше 30.000 символов в сниппете

Answer 1

Для вывода подсказок можно применить тег SVG <title>...</title>

Если вы хотите реализовать вывод подсказки, например, какого-то участка карты, то необходимо обернуть path, который рисует этот участок групповым тегом <g>.

И разместить внутри него двойной тег <title> с поясняющим текстом.

Пример:

<g>
<title>   "UT" - Utah
      State capital city - Salt Lake City

      City  186,440

 </title> 
      <path d="M0 0...."/>
</g>
