This example visualizes word frequency data as a word cloud using the d3.layout.cloud() plugin, with word size mapped to frequency and rotation depending on text length. Words are colored red if they match a set of keywords, otherwise black, with 75% opacity. The visualization uses both SVG for the rendered words and canvas for collision detection behind the scenes, with animation as words are placed iteratively. The layout centers the cloud in a 500x500 SVG and uses a spiral placement algorithm to prevent overlaps.

AI-generated description

This is the code for Chapter 5, Figure 30 from D3.js in Action used to create a word cloud with semantically meaningfully word color and rotation using d3.layout.cloud() (a layout created by Jason Davies that does not come in core D3).

Word Cloud-3

This example displays a word cloud visualization using the d3.layout.cloud plugin, which arranges words from a TSV data file based on their frequency values. The code filters the dataset, maps each entry to a text-size pair, and uses the cloud layout with custom rotation, padding, and the Impact font. Words are rendered as SVG text elements with colors from a category20c scale, appearing animated as the layout algorithm places them across a 500×500 canvas area.

Word Cloud Example

This example presents a word cloud visualization that arranges text tags by frequency, with larger words representing higher values in the input data. The layout algorithm, based on Jason Davies’s implementation, places words using an Archimedean spiral to avoid collisions. The code uses the `d3.layout.cloud` API with `.size()`, `.padding()`, `.rotate()`, and `.font()` configurations. After layout, the `d3.select("body").append("svg")` chain renders the results, applying font size and family via inline styles, with animated placement driven by the `setInterval` timer in the cloud layout process.

Word Cloud

This word cloud uses D3’s `d3.layout.cloud` to position words by frequency, with font size scaled by each term’s count. The layout runs inside a force simulation, and the rendering draws the words onto an SVG canvas using `d3.select` and `text` elements. The visualization reads a local JSON dataset of words and counts, then animates the cloud’s appearance with a smooth rotation and fade-in transition. Colors are applied from a categorical palette to differentiate word groups, while the overall layout adapts to the container’s size.

Word Cloud Example

This example demonstrates a word cloud visualization, where words from a CSV file (datas.csv) are displayed with varying font sizes proportional to their frequency counts. The visualization is built using D3.js v3 and the custom `d3.layout.cloud.js` library, which implements the word layout algorithm. The code uses D3's linear scale for color mapping and renders the words as SVG text elements. Animated placement occurs through the library's internal timer steps, positioning each word using a spiral placement algorithm.

Word Cloud Example

This example displays a word cloud of physics-related terms, with font size encoding each word's frequency from the provided dataset. It uses the `d3.layout.cloud` plugin to compute the layout and renders the result as SVG text elements with D3 v3. The cloud rotates words at zero degrees and applies a grayscale color scale based on frequency. An animation gradually places each word into position as the layout algorithm runs.

D3 Word Cloud

This D3 Word Cloud example arranges a small set of words, such as “out,” “just,” and “eventbrite,” into a visual frequency layout. The words are weighted and displayed using the Impact font, with sizes proportional to their associated values. Built with D3 version 3, the visualization uses the `d3.layout.cloud` library to perform the layout calculation. The rendering occurs as SVG text elements, which are positioned and rotated within a 600x600 pixel canvas based on the algorithm’s output.

Test

This example demonstrates a word cloud layout algorithm that arranges words at varying font sizes and orientations without overlap. The visualization uses the d3-cloud library with d3-dispatch to place words in a spiral pattern, while d3-selection renders the resulting text elements as SVG. The code includes both browser-based and Node.js implementations, with the Node version using the canvas package to compute word placements. The layout is animated through a step timer that processes words incrementally, and the rendering displays words in the Impact font with random sizes between 10 and 100 pixels.

Word Cloud-3

This visualization displays a word cloud built from frequency data in a TSV file, using font size to encode the magnitude of each term. The words are rendered as SVG text elements with random rotations and a categorical color scale. The layout is computed with the `d3.layout.cloud` plugin, which uses a collision detection algorithm to place words without overlapping. Data is loaded via `d3.tsv` and processed with array methods before the cloud is drawn and animated by the plugin’s step function.
