This is done by seeking to minimize each class's average deviation from the class mean, while maximizing each class's deviation from the means of the ...
Jenks made a breakthrough with the development of the "Jenks Natural Breaks Optimization Algorithm," commonly known as the Jenks Natural Breaks Algorithm, in a 1967 paper. [16] This algorithm is widely used in cartography and GIS to classify data into natural groupings, thereby enhancing the visual representation of data on maps.
