D3.js Tree Node Layout Remove Root Node

Please, I am searching for a solution to not display the root node and connecting lines to it. I have already tried to append multiple append('svg:svg') and populate those with roo

Solution 1:

You can just pop out the last node you make in update(source), which is the root node. like this:

    // Compute the new tree layout.
    var nodes = tree.nodes(root).reverse();
    nodes.pop()
