Vaping Twitter
This radial tree visualization maps the sentiment of vaping-related tweets, branching from a central root into positive, negative, and neutral categories, with sub-branches for marketing, personal, and other content. The code loads hierarchical CSV data with `d3.csv`, structures it using `d3.stratify`, and computes the radial layout with `d3.tree`. Links are drawn using `d3.linkRadial`, while nodes are positioned via custom trigonometric functions. The SVG rendering applies light blue, semi-transparent strokes, and each leaf node displays a label with white-text shadowing for readability.
