How to make a cluster diagram together with remoteObjectManager?

Question

Yandex maps

Hello!
I want to display cluster labels in the form of a chart. I do it like this:
JS:

var remoteObjectManager = new ymaps.RemoteObjectManager(url, {
    splitRequests: false,
    clusterHasBalloon: true,
    clusterHasHint: false,
    clusterIconLayout: 'default#pieChart',
    clusterIconPieChartRadius: 25,
    clusterIconPieChartCoreRadius: 10,
    clusterIconPieChartStrokeWidth: 3,
});

The FeatureCollection element coming from the server:

$item['id']                           = 1;
$item['type']                         = 'Cluster';
$item['number']                       = 10;
$item['bbox']                         = // ...;
$item['properties']['balloonContent'] = '';
$item['geometry']['type']           = 'Point';
$item['geometry']['coordinates'][0] = (float) $cluster['lat'];
$item['geometry']['coordinates'][1] = (float) $cluster['lng'];

How should information be sent from the server to form a chart?

Understood. In php you need to add:

$item['properties']['data'] = [
  ['weight' => 5, 'color' => '#224080'],
  ['weight' => 3, 'color' => '#408022'],
  ['weight' => 2, 'color' => '#802240'],
];
