This interactive tree chart, titled “MY Tree ICE-8,” visualizes a hierarchy of tech layoffs categorized by continent, country, and company. The code uses the D3.js library (version 3.5.17) to construct the tree layout and render it as an animated, scalable vector graphic (SVG). D3’s `d3.layout.tree` and diagonal path generator create the node-link diagram, with distinct shapes and colors (circles, rectangles, and squares) for each hierarchy level. The visualization includes a legend explaining the shape mappings, and its interactive cursor styling suggests nodes can be clicked or hovered.
