Using d3-scale-cluster

A simple interface for seeing the classes selected by d3-scale-cluster for your own data, colours and required number of classes.

You can enter your own colour choices (or select good colours from ColorBrewer etc).

I made this tool as I needed to manually create the colour schemes for use in other mapping applications.

Number of classes:

First colour:

Last colour:

Type or paste your data (numbers). One number per line. No blank lines (they will be treated as zeroes).

Enter your own data (or use the prefilled data), select the number of classes, and click Refresh to see the results.
