A family tree of programming domains is shown as a vertical hierarchy, with colored nodes representing technology categories (Technology, Software, Hardware, AI) and their subcategories. The visualization uses D3.js v7's `d3.stratify()` to convert flat parent-child data into a hierarchy, then positions nodes with the `d3.tree()` layout. Links are drawn as vertical paths using `d3.linkVertical()`, while circles and text labels are placed at computed coordinates. The data is a static array of programming domains, rendered as an SVG with colored nodes by depth level.

Tree

This example shows a horizontal tree diagram of technology domains, with three levels of depth branching from a root "Technology" node into categories like Programming Languages, Web Technologies, and Data & AI, and further into specific tools and languages. The visualization uses D3.js v7 with the `d3.hierarchy` and `d3.tree` layout APIs to compute node positions, and `d3.linkHorizontal` to draw smooth curved links between parent and child nodes. The SVG rendering distinguishes node hierarchy levels through color-coded fills: orange for the root, blue for first-level children, and green for second-level nodes, with each leaf labeled in small text.

tree

This example shows a hierarchical tree of programming languages, grouping frontend, backend, and data science categories with their child technologies. Developed with D3 v7, it uses `d3.hierarchy` and `d3.tree` to compute node positions, then renders curved `d3.linkVertical` paths for connections and SVG circles for nodes. Node colors vary by depth—orange for the root, teal for categories, and blue for leaves—with text labels above each circle. The static dataset is hard-coded in the script, and the output is a 900x500 SVG visualization.

ICE8_Tree_Programming_Languages

This visualization displays the programming language ecosystem as a three-level tree, with a root node branching into Web, Systems, and Data Science categories, and then into specific languages and technologies. Categories are color-coded by depth: orange for the root, green for the middle tier, and blue for leaves, with all labels rendered directly on circular nodes. The code uses D3's `d3.stratify()` to build the hierarchy from a parent-child dataset, then applies a `d3.tree()` layout with a vertical link generator (`d3.linkVertical()`) to position nodes. SVG circles and text elements are appended via D3's `selectAll().join()` pattern, with each node's fill color determined by its `depth` value.

Tree

A hierarchical tree diagram displays the structure of programming languages, grouped into Web, System, and Data categories. The visualization uses a static dataset defined in JavaScript. D3.js v7 with an SVG rendering approach draws the graph, employing `d3.hierarchy` and `d3.tree` to compute the layout. Nodes are represented as colored circles, color-coded by depth using `d3.scaleOrdinal` with `d3.schemeCategory10`, while links and text labels are appended via D3's data-join methods. The tree is oriented horizontally, placing parent-child connections left-to-right.

Family Tree

A family tree visualization renders hierarchical relationships as an SVG diagram. Colored circles mark each person, with blue, yellow, and orange indicating their depth in the tree, while curved paths connect parents to children. The example uses D3 v5, but notably relies on the missing `d3.stratify` and `d3.tree` APIs, which are not part of the standard D3 library. The code manually positions nodes and links using the x and y coordinates from those undefined functions, with hard-coded data listing individuals and their parents.

Family Tree

A family tree uses a branching layout to show relationships among Intel-related products, from the root Intelchip down to microprocessors, microcontrollers, graphics, and Nvidia subcategories. The code applies d3.stratify and d3.tree to compute node positions, rendering circles for each item and animated paths for the connections. Colors distinguish generations, with SVG transitions animating both the links and circle radii.

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.

Fork of Tree

This example presents a hierarchical tree of programming languages organized by development category, using color-coded nodes to distinguish depth levels. The visualization renders a static tree layout with vertical links connecting parent and child nodes, displaying category names like Web Development and Data Science alongside specific languages. Built with D3 v7, the code uses `d3.hierarchy` to structure the data and `d3.tree` for layout, while `d3.linkVertical` generates the connecting paths. SVG circles and text labels are positioned via transform attributes, with colors assigned based on node depth.
