Tree diagram using flat data with v4
This tree diagram visualizes hierarchical relationships from flat, parent-child data, rendering nodes and curved links in an SVG. It uses d3.stratify() to convert the flat data into a hierarchy, then applies the d3.tree() layout to position nodes. The code assigns node names via treeData.each(), draws paths for links with cubic Bézier curves, and styles circles and text for internal and leaf nodes. The example demonstrates d3 v4’s approach to handling non-nested data, with margins and dimensions set explicitly for the SVG output.
AI-generated descriptionThis is a tree diagram that used data from a 'flat' format. It has been written with d3.js v4 and is based on the simple horizontal version here
This is designed to be used as part of documenting an update to the book D3 Tips and Tricks to version 4 of d3.js.
