-`plot-light` provides functionality for rendering vector graphics as SVG.
-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.
-It builds upon `blaze-svg` by adding type-safe combinators, geometry primitives and functionality.
+`plot-light` provides functionality for rendering 2D graphics. It is geared in particular towards scientific plotting, and it is called "light" because it only requires a few common Haskell dependencies.
+It builds upon `blaze-svg` and `JuicyPixels` by adding type-safe combinators, geometry primitives and high-level graphing functionality.
