dont

make svg donuts with js.

methods

`dont.segment(cx, cy, ri, ro, ds, de[, offset])`

draws a donut segment, returns an svg path;

cx - center x
cy - center y
ri - inner radius from center (the hole)
ro - outer radius from center (the edge)
ds - segment starts at degrees
de - segment ends at degrees
offset - degrees offset; shift the start of the donut circle

`dont.rad(degrees[, offset])`

converts degrees to radians, with an offset of degrees

`dont.area(ri, ro, ra)`

calculates and returns the radius from center for a segment area to be in proportion to the area of the whole segment. if you want a comparable areas instead of comparable radii. the area of the hole is taken into account.

(send a pull request if you get what i mean and can explain it more eloquent).

ri - inner radius from center (the hole)
ro - outer radius from center (the edge)
ra - ratio of area in relation to total segment area

`dont.draw(data [, options])`
