JavaScript diagramming library

<p>The <code>'connectionRatio'</code> link anchor function places the anchor of the link at a point at a specified ratio of the reference link's length (from reference link's source). It accepts one argument, which can be passed within the <code>linkAnchor.args</code> property:</p>

<table>
    <tr>
        <th>ratio</th>
        <td><i>number</i></td>
        <td>The length ratio of the target anchor. Default is <code>0.5</code>, meaning the midpoint of the reference link.</td>
    </tr>
</table>

<p>Example:</p>

<pre><code>link.source(link2, {
    linkAnchor: {
        name: 'connectionRatio',
        args: {
            ratio: 0.25
        }
    }
});</code></pre>
