LineTo

Draw line between two DOM elements.

Example

import LineTo from 'react-lineto';

function render() {
    return (
        <div>
            <div className="A">Element A</div>
            <div className="B">Element B</div>
            <LineTo from="A" to="B" />
        </div>
    );
}

If using multiple instances of <LineTo /> inside separate components, you must provide a unique key for each of the container divs.
