longDescription = ''
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.
