         * There are three available algorithms:
         *
         * 1) `grid` - grid-based clustering technique. Points are assigned
         * to squares of set size depending on their position on the plot
         * area. Points inside the grid square are combined into a cluster.
         * The grid size can be controlled by `gridSize` property
         * (grid size changes at certain zoom levels).
         *
         * 2) `kmeans` - based on K-Means clustering technique. In the
         * first step, points are divided using the grid method (distance
         * property is a grid size) to find the initial amount of clusters.
         * Next, each point is classified by computing the distance between
         * each cluster center and that point. When the closest cluster
         * distance is lower than distance property set by a user the point
         * is added to this cluster otherwise is classified as `noise`. The
         * algorithm is repeated until each cluster center not change its
         * previous position more than one pixel. This technique is more
         * accurate but also more time consuming than the `grid` algorithm,
         * especially for big datasets.
         *
         * 3) `optimizedKmeans` - based on K-Means clustering technique. This
         * algorithm uses k-means algorithm only on the chart initialization
         * or when chart extremes have greater range than on initialization.
         * When a chart is redrawn the algorithm checks only clustered points
         * distance from the cluster center and rebuild it when the point is
         * spaced enough to be outside the cluster. It provides performance
         * improvement and more stable clusters position yet can be used rather
         * on small and sparse datasets.
         *
         * By default, the algorithm depends on visible quantity of points
         * and `kmeansThreshold`. When there are more visible points than the
         * `kmeansThreshold` the `grid` algorithm is used, otherwise `kmeans`.
         *
         * The custom clustering algorithm can be added by assigning a callback
         * function as the type property. This function takes an array of
         * `processedXData`, `processedYData`, `processedXData` indexes and
         * `layoutAlgorithm` options as arguments and should return an object
         * with grouped data.
         *
         * The algorithm should return an object like that:
         * <pre>{
         *  clusterId1: [{
         *      x: 573,
         *      y: 285,
         *      index: 1 // point index in the data array
         *  }, {
         *      x: 521,
         *      y: 197,
         *      index: 2
         *  }],
         *  clusterId2: [{
         *      ...
         *  }]
         *  ...
         * }</pre>
         *
         * `clusterId` (example above - unique id of a cluster or noise)
         * is an array of points belonging to a cluster. If the
         * array has only one point or fewer points than set in
         * `cluster.minimumClusterSize` it won't be combined into a cluster.
