This interactive tree chart visualizes tech industry layoffs, organizing companies by sector and country. The D3.js (version 3.5.17) layout renders an SVG hierarchy with distinct node shapes and colors: cyan circles for industries, aqua rectangles for countries, and yellow squares for companies, all linked by white strokes on a tan background. A fixed legend explains the mappings. The static dataset includes four industries—Finance, Security, Education, and Healthcare—with associated countries and named startups, though the animation capability implied by the metadata is not implemented in the shown code.
