This hierarchical tree visualization maps programming languages by paradigm and family, showing the relationships from root categories down to individual languages. It uses D3 v7’s `stratify` and `tree` APIs to process CSV data and compute the layout, while custom `symbol` shapes (circle, square, diamond, triangle) and an ordinal color scale distinguish each depth level. Interactive tooltips display node names and layer types on hover, with a legend explaining the four tiers. The visualization renders as SVG with horizontal link paths connecting nodes.

Tree

This visualization displays a hierarchical tree of programming languages, organized by paradigms and categories, with node shapes indicating the level in the hierarchy: a circle for the root, squares for paradigms, triangles for categories, and rounded rectangles for individual languages. The data is defined as a JavaScript object and rendered using D3.js v7, specifically relying on the `d3.hierarchy` and `d3.tree` layout functions to position nodes and links. The SVG output uses custom styling for links and labels, and a fixed-size SVG canvas at 1200x800 pixels.

tree

This example displays a hierarchical tree of programming languages, organizing them into compiled and interpreted categories with individual language leaves. The visualization uses d3.csv to load the data, d3.stratify to convert the flat table into a hierarchy, and d3.tree to compute the layout. Links are drawn with d3.linkHorizontal, while nodes differentiate types using shapes—circles for parent categories and diamonds for leaves—with a d3.scaleOrdinal assigning colors by depth. SVG rendering presents the final structure against a styled page background.

ICE8-Tree-CM

A vertical D3.js tree visualizes programming languages across four layers: root, paradigm, language, and ecosystem. Color encodes paradigm (functional, object-oriented, procedural, scripting), while shape distinguishes each level—circle for root, diamond for paradigm, square for language, and triangle for ecosystem. Built with D3 v7 and SVG rendering, the tree includes hover tooltips, a legend, and inline self-tests calling `d3.stratify` to verify the data structure. The flat row data with parent-child IDs is converted into the tree layout, with accessible labels and ARIA attributes on the SVG element.

ICE_8_NIHARIKA_TREES

A hierarchical tree visualization maps programming languages by paradigm and family, using a dataset loaded from a CSV gist. The visualization uses distinct shapes and colors for each layer: a diamond for the root, rounded rectangles for paradigms and families, and circles for individual languages. Built with D3 v7, the code employs `d3.stratify()` to build the hierarchy and `d3.tree()` for layout, rendering curved links and nodes as SVG elements with a dark gradient background.

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.

A_8_part2

This visualization shows a hierarchical tree of programming languages, organized by paradigm and family, with each node’s color indicating its depth in the hierarchy. Built with D3 v6, it uses `d3.stratify` to convert CSV data into a hierarchy, `d3.tree` to compute the layout, and `d3.linkHorizontal` to draw curved links. Nodes are rendered as SVG circles with labels, positioned via the tree layout’s x and y coordinates, and colored using a `d3.scaleOrdinal` with a per-depth color range.

tree diagram

A hierarchical tree diagram organizes programming languages into a root, categories, and individual languages. Each level is distinguished by a unique color, with nodes and labels displayed across a horizontal layout. The visualization uses D3.js v7, specifically the `d3.stratify` and `d3.tree` APIs to structure and position the hierarchy. Links are drawn with `d3.linkHorizontal`, and nodes are circles colored by depth, rendered as SVG within a `viewBox` canvas. A small legend clarifies the color mapping for root, category, and language depths.

ice8_task2

This radial tree diagram shows the hierarchical structure of programming paradigms, branching from a central root into Functional, Object-Oriented, Logic, and Procedural categories, with further subdivisions down to individual languages. The visualization uses a custom D3.js v7 tree layout with SVG rendering, where nodes are represented by different geometric shapes—diamonds for the root, rounded rectangles for paradigm categories, circles for sub-families, and triangles for leaf languages. Links are drawn using d3.linkHorizontal with curved paths, while a d3.scaleOrdinal color scheme distinguishes the four main paradigm branches. The data is hardcoded as a nested JavaScript object.
