This node-link diagram visualizes the relationships among Facebook food pages, using a force-directed layout to position nodes and edges. The graph is rendered as an SVG, with nodes as blue circles and labels placed nearby. The code utilizes the D3.js v7 library, specifically leveraging the `d3.forceSimulation`, `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` APIs to compute the layout. The data originates from the networkrepository.com fb-pages-food dataset, loaded from `nodes.csv` and `links.csv` files. The simulation continuously updates node, label, and link positions on each tick event.

Assignment 8 Node-link diagram

This node-link diagram visualizes the connections between food-related Facebook pages and their chefs. The graph uses a force-directed layout where each node represents a page and links show relationships from an edges.csv file. The code loads data with `d3.csv`, then applies `d3.forceSimulation` with `forceLink` and `forceManyBody` to position nodes and edges. The SVG rendering updates positions on each tick, placing labels directly on nodes and styling links with a gray stroke.

Assignment 8 Force-Directed Node-Link Diagram

This force-directed node-link diagram visualizes a food network, with nodes representing individual food items and links showing relationships between them. The graph uses a physical simulation to position nodes, which are drawn as small green circles connected by black lines, and includes tooltips for interaction. The visualization is rendered with D3 v6, using `d3.forceSimulation` with `d3.forceCenter`, `d3.forceManyBody`, and `d3.forceLink` to drive the layout. Data is loaded from two external CSV files containing node and edge definitions, with the SVG output sized at 2500 by 2000 pixels.

A8 Node-Link Diagram D3 (force-directed)

This visualization shows a force-directed node-link diagram of Facebook page connections using data from CSV files, with interactive hover tooltips displaying node names. The code builds the network using D3.js v7’s `d3.forceSimulation`, applying link, charge, and center forces to position nodes and edges. SVG lines represent links and circles represent nodes, which users can drag via `d3.drag`. The simulation updates positions on each tick, while a styled `#tooltip` div appears on mouseover. Data loads through `d3.csv` and `d3.text` with manual parsing via `d3.csvParseRows`.

A8 Node-Link Diagram D3 (edge-bundling)

This example combines a force-directed network diagram with an adjacency matrix to visualize Facebook page connections in the food category. The network uses curved paths generated with D3’s `d3.curveBundle` for edge bundling, while `d3.forceSimulation` handles node positioning and dragging. Hovering over a node highlights its corresponding row and column in the matrix, with tooltips showing node names. Both visualizations load CSV data for nodes and edges, rendering in SVG.

D3 Node-Link Diagram

This example shows a node-link diagram of social network data, using a force-directed layout to position 16 nodes and their connecting links. The visualization uses D3 v7's `d3.forceSimulation` with `forceManyBody`, `forceLink`, and `forceCenter` to calculate the layout, while rendering nodes as SVG circles and edges as lines with animated tick updates. Node colors come from `d3.scaleOrdinal` with the `schemeSet1` palette, and hovering a node triggers a tooltip via mouseover events. Data is loaded from a CSV file containing source, target, and link values.

A8 - node-link diagram with force-directed layout

This example shows a force-directed node-link diagram of the Zachary Karate Club social network, with orange nodes and gray edges. It uses the D3 forceSimulation API to compute the layout through charge, link, and center forces, updating the SVG positions on each tick. Node labels appear in a tooltip on mouseover, built with D3’s selection and transition API. The graph renders as an SVG with animation, driven by the react framework, and the data is loaded from a remote CSV file.

A8 - Node-link diagram with force-directed layout

This example displays a food network as a node-link diagram with a force-directed layout. It uses D3.js v7's `d3.forceSimulation` with link, charge, and center forces to position nodes and edges. Node interactions include hover effects that enlarge circles and reveal a tooltip with the node ID. Data is loaded from a CSV file via `d3.csv`, and the visualization is rendered as animated SVG elements.

Assignment 8 node-link diagram (force-directed)

A circular node-link diagram arranged by a hierarchy, with edges bundled using D3's `d3.lineRadial` and `d3.curveBundle` to show connections between food-related entities. The chart, rendered as an SVG, draws food nodes from `food_nodes.csv` and edges from `food_edges.csv`, coloring links orange on hover to highlight a selected node's relationships. A slider adjusts the tension of the bundled curve, interactively reshaping the edge paths. The data, attributed to “Xhy51”, likely represents a network of food brands and chefs.
