build_shape

Easy-to-use functions to generate 2-7 sets Venn plot in publication quality.
'ggVennDiagram' plot Venn using well-defined geometry dataset and 'ggplot2'. The shapes of 2-4 sets
Venn use circles and ellipses, while the shapes of 4-7 sets Venn use irregular polygons (4 has both forms), which
are developed and imported from another package 'venn', authored by Adrian Dusa. We provided internal functions to
integrate shape data with user provided sets data, and calculated the geometry of every regions/intersections
of them, then separately plot Venn in three components: set edges, set labels, and regions.
From version 1.0, it is possible to customize these components as you demand in ordinary 'ggplot2' grammar.
