I develop a Application in with the help of JDiagram In java swing witha tree layout

TreeLayout tl = new TreeLayout();
tl.setType(TreeLayoutType.Radial);
tl.setLevelDistance(50);
tl.setLinkStyle(TreeLayoutLinkType.Rounded);

I need the same in java Script
I tried
var treeLayout = new TreeLayout();
treeLayout.linkType = TreeLayout.LinkTypeRounded;
//treeLayout.TreeLayoutType=TreeLayoutType.Radial;
//treeLayout.linkType = TreeLayoutLinkType.Rounded;
//treeLayout.setTreeLayoutLinkType(TreeLayoutType.Radial);

But unable to get the exact same as Java Swing alyout

Thanks
