Hull Geom

Wiki ▸ API Reference ▸ Geometry ▸ Hull Geom

# d3.geom.hull([vertices])

If vertices is specified, returns their convex hull, using the default x- and y-coordinate accessors. The convex hull is represented by an array containing a subset of the input vertices, arranged in clockwise order.

If vertices is not specified, creates a new hull layout with the default settings.

# 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]; }
