Area chart with glowing dot markers

<!--
  Замена библиотеки: см. c-chart-13.vue / docs/PORTING.md §19/§27. Свечение
  (`feGaussianBlur`/`feComposite` SVG-фильтры) и маркеры точек на линии
  (`dot`/`activeDot`) не переносятся — `AreaChart` не принимает произвольный
  SVG-фильтр на линию/область и не рисует точки-маркеры по умолчанию.
