This colorful family tree visualization displays hierarchical relationships using a custom dataset of family names. The D3 v7 code builds an SVG rendering with a `d3.hierarchy` layout to position nodes and `d3.linkVertical` for the connecting edges. Each generation is distinguished through a `d3.scaleOrdinal` color scale, with interactive hover effects revealing tooltips that show the member name and generation depth.

Family Tree

This family tree visualization displays a hierarchical dataset of family members across several generations, with nodes colored by generation and connected by animated green links. Built with D3.js v6, the code uses the `d3.stratify()` utility to structure the parent-child data and `d3.tree()` to compute the layout. Nodes are rendered as SVG circles with a 1.5-second path-drawing transition, while text labels identify each person. Generation colors are assigned via a custom `setGenerations()` switch function, ranging from orange for the root to teal for deeper levels.

Family Tree

This interactive family tree visualization displays a hierarchical dataset of names, with each node colored according to its position and labeled with a person's name. The tree uses a left-to-right layout, where the depth of each node is reflected in the font size, making generational levels visually distinct. The visualization is built with D3 v5, employing the `tree`, `hierarchy`, and `linkHorizontal` APIs to compute the layout and draw connecting paths. All elements are rendered as SVG, with node labels and colors driven directly from the `data.json` file, and the entire graphic supports zooming via D3's `zoom` event.

This family tree visualization displays three generations of a family using a hierarchical tree layout. The D3.js visualization uses the `d3.hierarchy` and `d3.tree` APIs to position nodes and `d3.linkVertical` to draw connecting links as SVG paths. Each node is a colored circle, with distinct colors differentiating grandparents, parents, and children, including a node for "Me" and cousins. The SVG is fixed at 900x500 pixels, and the data is hard-coded as a JavaScript object within the script.

Assignment - 8 - 2.2

This family tree visualization displays a four-generation hierarchy using distinct colors and shapes for each layer: squares for the root, circles for grandparents, triangles for parents, and diamonds for children. Built with D3 v7, the example uses the `d3.hierarchy` and `d3.tree` APIs to compute the layout, `d3.linkVertical` for the connecting links, and `d3.symbol` with specific shape types and color functions per depth. Node positions are translated via SVG groups, with labels placed beneath each shape. The static data is embedded directly in the JavaScript code.

Family Tree

This interactive family tree visualizes genealogical connections using a parent-child hierarchy. Built with D3.js v3, it renders the structure as an SVG diagram with rectangular nodes and labeled links, supporting zoom and drag interactions. The data from `family-data.json` is loaded via `d3.json()`, and the layout is computed using `d3.layout.tree()`. Node colors vary by type, and each node includes a link label with directional information.

Family Tree

This interactive family tree visualization displays hierarchical relationships among family members using a collapsible tree layout. The D3.js v3 library constructs the diagram as SVG elements, with nodes represented as colored rectangles that branch from a root ancestor. The tree loads its structure from a JSON data file, and users can click individual nodes to expand or collapse their branches. The visualization includes zoom and pan capabilities through D3's behavior API, while a custom tooltip system displays additional information on hover.

Family Tree

This example displays a family tree as a hierarchical node-link diagram, with nodes colored by generation and green curved links connecting parents to children. The visualization renders in SVG and uses `d3.stratify()` to convert flat parent-child data into a hierarchy, then applies `d3.tree()` to compute the layout. Node circles, connecting paths, and name labels are appended to the SVG using data-bound selections, with custom bezier curves drawn for each link.

Family tree

A family tree visualization maps a ten-person genealogy dataset with D3.js v6, using ancestor relationships to position nodes across four generations. Distinct colors (blue, lawngreen, magenta, white) encode each generation’s depth. The rendering uses SVG elements with animated transitions: paths draw over two seconds to form connections between parents and children, while circles grow to size 40 and labels appear with bold black text. The code leverages d3.stratify and d3.tree to compute hierarchical layout and link data.
