Natural Break (Jenks) node

Open koettert opened this issue 4 months ago • 1 comments

Natural breaks seems to be the default algorithm in ArcGIS and is commonly used https://en.wikipedia.org/wiki/Jenks_natural_breaks_optimization#Use_in_cartography

  • Node Name: Natural Break (Jenks)
  • The node input would be a KNIME table (does not need to contain a Geometry column)
  • Node dialog
    • Numerical column(s) to use
    • Number of classes (k)
  • Output would be the input table with an appended "Jenks class" column

We could use the https://pysal.org/mapclassify/generated/mapclassify.NaturalBreaks.html#mapclassify.NaturalBreaks method.
