This example pairs a force-directed graph with an adjacency matrix to visualize relationships from a food-themed CSV dataset. The graph uses `d3.forceSimulation` with link and charge forces to position nodes, while draggable circles represent entities. The adjacency matrix uses SVG rectangles, with fill opacity scaled by edge weight, and includes interactive tooltips on mouseover. Both views share the same node-link data, rendered in SVG with animation. The code relies on D3.js v6 APIs including `d3.csv`, `d3.forceLink`, `d3.drag`, and `.join()`.

Fork of Force-Directed Graph & Adjacency Matrix- D3.js

This visualization combines a force-directed graph with an adjacency matrix to explore restaurant connections from a CSV file. The node-link diagram uses d3.forceSimulation with drag interactions and animated ticks, while the matrix displays weighted links through cell opacity and tooltips. Both views render as SVG, with the matrix mapping food-related entities and their relationships using data from food.csv.

Assignment 7 -- Force-Directed Graph & Adjacency Matrix

This example presents a food-related dataset as both an interactive force-directed graph and an adjacency matrix. The force-directed layout uses `d3.forceSimulation` to position nodes and links, with drag behavior and animated tick updates. The adjacency matrix encodes edge weights through square opacity levels, rendered as SVG rectangles, with tooltips showing source and target IDs. Both visualizations are built with D3 v6, using SVG and animation, drawing from a CSV file.

Force Directed Graph

This example pairs a force-directed graph with an adjacency matrix to explore node-link relationships. The graph uses `d3.forceSimulation` with `forceLink`, `forceManyBody`, and `forceCenter` to position nodes, while drag and zoom interactions are enabled. Clicking a node or matrix cell highlights its row and column in the matrix and emphasizes connected links. Data is loaded from a CSV edges file, and rendering uses SVG circles, lines, and rectangles.

Force Directed Graph

A force-directed graph visualizes relationships among nodes in a network, with circle size reflecting group membership and link thickness indicating connection weight. The example loads CSV data from an external source and renders an interactive SVG where users can drag nodes, zoom, and click to highlight connected rows and columns in an accompanying adjacency matrix. It uses `d3.forceSimulation`, `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` for layout, with `d3.drag` and `d3.zoom` for interaction. The code also employs `d3.csv` for data parsing and builds the matrix using SVG rectangles and text elements.

Force Directed Graph

This example pairs a force-directed graph with an interactive adjacency matrix. The graph uses d3.forceSimulation with forceLink, forceManyBody, and forceCenter to layout nodes, and supports dragging. Clicking a matrix cell highlights the corresponding graph link, while the matrix also shows the dataset’s structure from the infect-dublin.edges file. The code uses d3.csv, d3.select, and reorder.js utilities for matrix permutation.

Force Directed Graph

This example pairs a force-directed graph with an adjacency matrix to explore node-link diagrams and network connectivity. The graph uses D3’s `d3.forceSimulation` and `d3.forceLink` to position nodes, while the matrix encodes edge weights as cell opacity. Clicking a node or matrix cell highlights the corresponding row, column, and connected links. The code also enables drag interactions via `d3.drag` and zooming with `d3.zoom`, rendering everything as SVG.

Force Directed Graph

This example combines a force-directed graph with an adjacency matrix to visualize network data. The code reads a small dataset of nodes and links, rendering the graph as SVG circles and lines using `d3.forceSimulation`, `forceLink`, `forceManyBody`, and `forceCenter`. Users can drag nodes and apply zoom via `d3.zoom`. Clicking a node highlights its corresponding row and column in the adjacency matrix, which is built with D3 selections and `rect` elements. The visualization uses a color scale for node groups and includes a dropdown to order matrix rows.

Force Directed Graph

This example combines a force-directed node-link diagram with an adjacency matrix to compare two visualizations of the same graph data. The SVG diagram uses `d3.forceSimulation` with `forceLink`, `forceManyBody`, and `forceCenter` to position nodes, while drag interactions and zoom controls are enabled via `d3.drag` and `d3.zoom`. The adjacency matrix displays link weights through cell opacity, and clicking a node or matrix cell highlights corresponding links and rows in both views. The code loads data via `d3.csv`, `d3.tsv`, and `d3.text`, rendering with D3 v6.
