-- `plot-light` provides functionality for rendering vector
-- graphics in SVG format. It is geared in particular towards scientific plotting, and it is termed "light" because it only requires a few common Haskell dependencies and no external libraries.
--
-- == Usage
--
-- To use this project you just need `import Graphics.Rendering.Plot.Light`. If GHC complains of name clashes you can import the module in "qualified" form.
--
-- If you wish to try out the examples in this page, you will need to have these additional import statements:
--
-- @import Text.Blaze.Svg.Renderer.String (renderSvg)@
-- 
-- @import qualified Data.Colour.Names as C@

module Graphics.Rendering.Plot.Light (
  -- * Graphical elements
  rectCentered, circle, line, axis, text, polyline,
  -- ** Element attributes
  LineStroke_(..), StrokeLineJoin_(..), TextAnchor_(..),
  -- ** SVG utilities
  svgHeader,
  -- * Types
  Frame(..), Point(..), LabeledPoint(..), Axis(..),
  -- * Geometry
  -- ** Vectors
  V2(..),
  -- ** Matrices
  Mat2(..), DiagMat2(..), diagMat2,
  -- ** Primitive elements
  origin, e1, e2,
  -- ** Vector operations 
  norm2, normalize2,
  -- ** Vector construction
  v2fromEndpoints, v2fromPoint,
  -- ** Operations on points
  movePoint, moveLabeledPointV2, fromUnitSquare, toUnitSquare,
  -- ** Typeclasses
  AdditiveGroup(..), VectorSpace(..), Hermitian(..), LinearMap(..), MultiplicativeSemigroup(..), MatrixGroup(..), Eps(..)
