A hierarchical dataset from a CSV file is visualized as a force-directed graph, where nodes are sized proportionally to a square-root-scaled `data` value and rendered as circular foreign objects containing wrapped text. SVG lines connect parent and child nodes based on the data's structure. The visualization uses D3 v4's `d3.stratify`, `d3.forceSimulation`, `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCollide` to position nodes, which are grouped elements containing a circle and an `foreignObject` with HTML content. The layout dynamically adjusts node positions and text fit during each simulation tick.

force directed test

This example shows a hierarchical dataset rendered as a force-directed network of circular nodes, where each node’s size and text content are scaled based on a numerical data value. The visualization uses `d3.forceSimulation` with a combination of link, charge, center, and collide forces to position nodes, while SVG `<line>` elements draw the connecting edges. Node labels are displayed inside circular `foreignObject` containers with HTML styling, with text clipped to fit. The underlying data is loaded from a CSV file via `d3.csv` and structured into a hierarchy using `d3.stratify`.

force directed text fit done

A force-directed layout arranges a hierarchical dataset as a bubble chart, with circle size proportional to each node’s value and text labels fitted inside. Nodes cluster by parent, while lines show parent–child links. The simulation uses `d3.forceSimulation` with `forceLink`, `forceManyBody`, `forceCenter`, and `forceCollide`. Labels are rendered as SVG text with font sizes computed per tick and node radius. Data loads from a CSV via `d3.csv`, and colors come from `d3.scaleOrdinal(d3.schemeCategory10)`.

force directed text fit labels

This example shows a hierarchical dataset rendered as a force-directed graph, where parent nodes are connected to child nodes by lines, and each leaf node displays its label text inside a circle sized by its value. The visualization uses d3.forceSimulation with forces for link distance, charge, centering, and collision, while text is fit to each circle by computing a font size based on the circle’s radius and the text length. Nodes and links are drawn as SVG elements, with data loaded from a CSV file via d3.csv and a stratify layout, and labels are added for leaves using underscore.js.

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 - Simple

This example shows a force-directed graph built from hierarchical data stored in a flat CSV file. The visualization converts the parent-child relationships into a network layout using `d3.stratify`, then renders the resulting nodes as circles positioned by the `d3.forceSimulation` with link, charge, and center forces. The example uses D3 v5 to load the data with `d3.csv`, applies a paired color scale to nodes based on their parent, and draws the output as SVG elements. The code includes commented-out drag and tooltip interactions that are not active in the final rendering.

Force-Directed Tree II

A force-directed tree visualization displays the hierarchical file structure of the D3.js library, with nodes representing individual modules and paths. The layout is computed using `d3.forceSimulation` with `d3.forceManyBody`, `d3.forceLink`, and positional forces, rendering to a Canvas 2D context via `context.arc` and `context.lineTo`. Nodes are draggable, with drag behavior implemented through `d3.drag` and a simulation `find` query. Data originates from a CSV file parsed by `d3.csv` and structured with `d3.stratify`.

Force Directed Graph - Simple

A force-directed graph displays hierarchical data through a network of linked nodes. The example loads a flat CSV file, converts it into a tree hierarchy using `d3.stratify`, and renders it with SVG paths and circles. The layout is computed by `d3.tree`, with curved links drawn between parent and child nodes. The visualization uses `d3.csv`, `d3.hierarchy`, and `d3.select` to structure and display the data from `data.csv`, showing relationships from "Top Level" down to individual leaf nodes.

Force Directed Graph - Simple

This example displays a simple force-directed graph built from a CSV file containing hierarchical data, showing parent-child relationships as an interactive tree layout with curved links and labeled circular nodes. The code uses d3.v5’s `d3.csv`, `d3.stratify`, and `d3.hierarchy` to transform the flat tabular data into a tree structure, which is then rendered as an SVG via the `d3.tree()` layout. Nodes are drawn as circles with text labels, connected by cubic Bézier paths, with styling applied through CSS classes.
