d3-scale-cluster
A D3 scale that clusters continuous data into discrete groups using a 1D clustering algorithm, similar to quantile scales.
What is d3-scale-cluster?
d3-scale-cluster is a custom D3.js scale that clusters continuous numeric data into discrete groups using a 1-dimensional clustering algorithm. It solves the problem of creating more intuitive data groupings for visualizations like choropleth maps, where traditional quantile or quantize scales might produce misleading breaks.
Data visualization developers using D3.js who need to create color scales or data bins based on natural clustering of values, particularly for thematic mapping or histogram-like displays.
Developers choose d3-scale-cluster because it provides more meaningful data groupings than D3's built-in quantile/quantize scales by identifying natural breaks in data distributions, leading to clearer and more accurate visual representations.
