Hi, I am new to windy.

I am trying to draw semi circle on map, so i am using an extension called 'Leaflet-semicircle'.

but when i add the semi circles into a featureGroup, then add featureGroup into M.map, it dosen't anything on windy.

Is something wrong?

windyInit(options, function (windyAPI) {

  var map = windyAPI.map;
  var latlng = [0, 0];

  function rangerings (latlng, opts) {
    opts = L.extend({
        count: 8,
        interval: 1000,
        direction: 120,
        spread: 60
    }, opts);

    var layer = L.featureGroup();
    for (var i = 1; i
