# d3.geom.hull()

Create a new hull layout with the default x- and y-accessors.

# hull(vertices)

Returns the convex hull for the specified vertices array, using the current x- and y-coordinate accessors. The returned convex hull is represented as an array containing a subset of the input vertices, arranged in counterclockwise order (for consistency with polygon.clip).

# hull.x([x])

If x is specified, sets the x-coordinate accessor. If x is not specified, returns the current x-coordinate accessor, which defaults to:

function(d) { return d[0]; }

# hull.y([y])

If y is specified, sets the y-coordinate accessor. If y is not specified, returns the current y-coordinate accessor, which defaults to:

function(d) { return d[1]; }
