+    Vg is an OCaml module for declarative 2D vector graphics. In Vg, images
+    are values that denote functions mapping points of the cartesian plane
+    to colors. The module provides combinators to define and compose these
+    values.
+
+    Renderers for PDF, SVG and the HTML canvas are distributed with the
+    module. An API allows to implement new renderers.
