Usage

` js
import arc from 'svg-arc';

// create SVG
const svg = document.createElementNS('http://www.w3.org/2000/svg', 'svg');
svg.setAttribute('viewBox', '0 0 300 300');

// create path
const path = document.createElementNS('http://www.w3.org/2000/svg', 'path');
path.setAttribute('fill', '#ddd');
svg.appendChild(path);

// set path
const d = arc({
x: 150,
y: 150,
R: 100,
r: 80,
start: 100,
end: 200,
});
path.setAttribute('d', d);

// When drawing a annulus, the attribute value of 'fill-rule' must be set to 'evenodd', otherwise the color cannot be filled correctly.
path.setAttribute('fill-rule', 'evenodd');
