# Naturalbreaks

Ports of fisher/jenks natural breaks algorithm with O(k×n×log(n)) complexity, engineered and described by Maarten Hilferink:

http://wiki.objectvision.nl/index.php/Fisher%27s_Natural_Breaks_Classification  

The code provided is a (nearly 1:1, as there is not much left for optimization) port of the corresponding C code that was

originally developed by Maarten Hilferink, © Object Vision BV and which can be found here:

http://wiki.objectvision.nl/index.php/CalcNaturalBreaksCode

My contribution is:

- a basic port to Java (src/main/java)

- a basic port to javascript (src/main/javascript) which allows direct execution in the browser to compute natural looking color scales.

Please see the contained unit tests for usage.
