Yandex Maps API Gridmap Module
Yandex.Maps API module for data visualization.
Gridmap is a graphical representation of some spatial data, where depending on the number of entered points cell of grid (hexogon or square) are painted in different colors.
Gridmap class allows to construct and display such representations over geographical maps.
Loading
Put module source code (gridmap.min.js) on your CDN.
Load both Yandex Maps JS API 2.1 and module source code by adding following code into <head> section of your page:
<script src="http://api-maps.yandex.ru/2.1/?lang=ru_RU" type="text/javascript"></script> <!-- Change my.cdn.tld to your CDN host name --> <script src="http://my.cdn.tld/gridmap.min.js" type="text/javascript"></script>If you use GeoJSON data:
<script src="http://api-maps.yandex.ru/2.1/?lang=ru_RU&coordOrder=longlat" type="text/javascript"></script> <!-- Change my.cdn.tld to your CDN host name --> <script src="http://my.cdn.tld/gridmap.min.js" type="text/javascript"></script>If you use npm:
<script src="http://api-maps.yandex.ru/2.1/?lang=ru_RU" type="text/javascript"></script>npm i --save git+https://github.com/yandex-shri-fx-team/ymaps-gridmap.gitrequire('ymaps-gridmap'); // Or with babel import 'ymaps-gridmap';Get access to module functions by using ymaps.modules.require method:
ymaps.modules.require(['Gridmap'], function (Gridmap) { var gridmap = new Gridmap(); });

Examples
Displaying gridmap over geographical map
ymaps.modules.require(['Gridmap'], function (Gridmap) {
const dataPoints = {
type: 'FeatureCollection',
features: [{
id: 'id1',
type: 'Feature',
geometry: {
type: 'Point',
coordinates: [37.782551, -122.445368]
}
}, {
id: 'id2',
type: 'Feature',
geometry: {
type: 'Point',
coordinates: [37.782745, -122.444586]
}
}]
};
const gridmap = new Gridmap(dataPoints);
gridmap.setMap(myMap);
});Demo
