Graphics.Rendering.Diagrams.Query
Description
The Query module defines a type for "queries" on diagrams, which
are functions from points in a vector space to some monoid.
Documentation
A query is a function that maps points in a vector space to values in some monoid. Queries naturally form a monoid, with two queries being combined pointwise.
The idea for annotating diagrams with monoidal queries came from the graphics-drawingcombinators package, http://hackage.haskell.org/package/graphics-drawingcombinators.
