A hierarchical tree visualization maps food categories such as Fruits, Vegetables, and Grains through types to individual items, with each node colored by depth and displaying nutritional calorie data via hover tooltips. The chart uses D3.js v7 with the `d3.hierarchy` and `d3.tree` layout functions to position nodes and links, rendered as an SVG with a custom tooltip div. Data is embedded inline from a food dataset, with link and node styling defined through CSS classes.

This visualization shows a hierarchical tree of food categories, breaking down foods from broad categories like Fruits and Vegetables into specific types and items. The tree uses colored nodes by depth—root, category, type, and item—with a legend explaining the color coding. Built with d3.v7, the code uses D3’s hierarchical layout to position nodes and links, rendered as SVG elements. Each node displays its label, and hovering reveals a tooltip with the item’s calorie count. The accompanying legend highlights the depth-based color scheme, while the chart container is styled with rounded borders and a clean, minimal design.

tree

This example shows a hierarchical tree diagram of food categories, from the root “Food” down to leaf items like Spinach, Carrot, Orange, and Apple. The visualization uses D3 v3’s `d3.layout.tree` to position nodes and links, with SVG rendering and animated transitions when the tree updates. Each node is color-coded by its type (e.g., type1 through type4), and links are drawn as stepped paths using `d3.line` with `curveStepAfter`. The code includes interactive zoom via `d3.behavior.zoom` and tooltips, with data pulled from an external JSON file.

Tree

A vertical tree diagram displays three levels of food categories, from the root "Food" down to fruits, vegetables, dairy, and their individual items. The SVG visualization uses D3 v7's `d3.stratify` and `d3.tree` layouts, reading hierarchical data from a local `food_tree.json` file. Node circles are colored by depth using a `d3.scaleOrdinal` with blue, orange, and green, while `d3.linkVertical` draws the connecting paths between parent and child nodes.

ICE8 - Task 2A

This visualization shows a three-level hierarchical tree of food categories, displaying a root node ("Food"), three category nodes (Fruits, Vegetables, Grains), and nine leaf items. The SVG rendering uses d3.hierarchy and d3.tree() to compute the layout, with d3.linkVertical() drawing the curved connections. Nodes are distinguished by shape and color: a yellow circle for the root, light-blue rounded rectangles for categories, and green diamonds for leaf items, each accompanied by text labels. The page includes a static, inline JavaScript dataset with no external data source.

Fork of Tree Graph

This tree visualization displays a hierarchical food categorization system, starting with a root "Food" node that branches into categories, subcategories, and individual items. The chart uses distinct geometric shapes for each depth level: circles for categories, rectangles for subcategories, and polygons for items, with a red root node. Built with d3.v7, the code constructs a hierarchical structure using `d3.stratify()` and `d3.tree()` functions, then renders the tree with `d3.linkVertical()` for connections. Labels appear above or below nodes depending on whether they have children, with the entire SVG output styled to fill the viewport.

ICE 8 Task 2B Kumar Danam

This example visualizes a hierarchical dataset of food categories—Food, Fruits, Vegetables, and Grains—as a vertical tree. It shows the nested structure with color-coded nodes by depth: blue for the root, orange for first-level children, and green for leaves, with links as curved paths. Built with D3.js v7, it uses `d3.hierarchy` and `d3.tree` to compute the layout, `d3.linkVertical` for the connecting paths, and SVG circles and text for node rendering. The hardcoded data is displayed in a 600×400 SVG.

Fruits

A hierarchical tree visualization displays fruit categories and their subtypes, with nodes colored by type and connected by labeled, directional links. The D3 v3 layout computes node positions, while SVG shapes and CSS styles render the interactive diagram. Users can click nodes and zoom or drag the view, with tooltips showing additional node information. The example also demonstrates loading D3 from a CDN and structuring data with external JSON files.

Fork of HTML Starter

This visualization shows a hierarchical food category tree, with food items as leaf nodes branching from broader categories like fruits, vegetables, and proteins. The code uses `d3.hierarchy` and `d3.tree` to compute the layout, then renders the structure as SVG paths and circles with `d3.linkVertical`. Node shapes vary by depth: a red rectangle for the root, blue circles for categories, and green circles for individual food items. Colors and node sizes are set directly in the D3 v7 code, which generates all elements dynamically from an inline JavaScript data object.
