/**
* Type of the algorithm used to combine points into a cluster.
* 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.
