Setting the License

To remove the watermark displayed on the apextree chart, you will need to purchase the license and set it like below

import ApexTree from 'apextree';

// set license key before creating any charts
ApexTree.setLicense('your-license-key');

const tree = new ApexTree(document.getElementById('svg-tree'), options);
const graph = tree.render(data);

You will receive your license key via email after purchasing a plan.
