optics.js is an open source JavaScript library which implements OPTICS clustering algorithm for browsers and node.js. For more detailed information about OPTICS clustering algorithm , refer to the below paper.

Ankerst, Mihael, et al. "OPTICS: ordering points to identify the clustering structure." ACM SIGMOD Record 28.2 (1999): 49-60.

Demo

optics(data, minPts, epsilon, getter, dist) returns an array of class Point.

• data: An array of data to be clustered.
• minPts: Defined in the forementioned paper.
• epsilon Defined in the forementioned paper.
• getter: Optional. If data contains other data structures (e.g. Object) rather than vectors (an array of numbers), you should specify how to get a vector from each element of data. The default value is an identity function (e.g. function(d){return d;}) which means each element of data is used as a vector.
• dist: Optional. A distance function which computes the distance between two vectors. If not specified, the Euclidan distance function is used.

Class Point contains the result of OPTICS clustering for one element of data

• point.datum
• point.isProcessed
• point.coreDistance
• point.reachability
• point.index
