WebFeb 4, 2024 · 1. In-Order Traversal. In in-order traversal, we traverse the left child and its sub-tree (s), then we visit the root and then traverse the right child and its sub-tree (s). It takes a “left-root-right” order. Before we take a look at a code sample for this algorithm, let’s try to outline the steps involved: Hierarchy Before you can compute a hierarchical layout, you need a root node. If your data is already in a hierarchical format, such as JSON, you can pass it directly to d3.hierarchy; otherwise, you can rearrange tabular data, such as comma-separated values (CSV), into a hierarchy using d3.stratify.
