This interactive family tree shows Arefa Patwary’s ancestors and relatives, with clickable nodes to expand or collapse branches. The SVG rendering uses d3.layout.tree to position nodes hierarchically and d3.svg.diagonal for curved links. Node clicks trigger a transition that smoothly animates the tree’s layout over 750 milliseconds. The hardcoded family data includes names like Nurun nahar begum and Shah alam Patwary. Styling is applied via CSS classes for nodes and links, with blue strokes for connections.
