This example demonstrates a real-time animated data join using D3’s `select`, `range`, and `selectAll` APIs within a React project. It generates a dynamic set of circles whose positions and radii oscillate based on a time variable, updating at 60 frames per second via `setInterval`. The code explicitly shows both the modern `.join()` method and its equivalent enter/merge/exit pattern, rendering SVG circles with live attributes. The visualization runs in a browser, auto-sizing to the window dimensions, and uses D3 v7.6.1 as its sole external dependency.

Fork of Fork of D3 Selection

This example displays a set of animated circles moving vertically and changing radius over time, driven by sine functions. The visualization uses D3.js v7 within a React-style structure, with the `vizData` function applying a data-join to update SVG `circle` elements. The animation loops at 60 frames per second via `setInterval`, recalculating positions and sizes based on a time variable. This demonstrates imperative selection and joining techniques on SVG elements, rendering dynamic shapes without external datasets.

Fork of D3 Selection Exploration

This example demonstrates dynamic data binding with D3 selections by rendering a set of circles that continuously change position, radius, and count over time. It uses the D3 v7 `select` and `range` functions along with the `join` method to manage enter, update, and exit states. The animation runs on a `setInterval` timer, updating a sine-wave-based dataset that controls each circle’s x-coordinate, y-coordinate, and radius. The visualization renders as an SVG canvas that fills the browser viewport, showing how D3’s data-join pattern efficiently handles fluctuating data sizes.

This example explores D3 data joins with animated circles. A set of circles moves vertically based on a sine wave, with the number of circles oscillating over time. The code uses d3.select, d3.range, and the selection.join method to update the SVG. Data is generated in makeData.js and rendered as circles with attributes for radius, cx, and cy, refreshed every 60 frames per second.

D3 Selection Exercise

This animated visualization demonstrates D3’s data-join and selection pattern by continuously updating a set of circles and connecting lines in an SVG scene. The code uses `selectAll` and `.join()` within `drawCircles` and `drawLines` to bind and update elements based on procedurally generated data from `makeCircleData` and `makeLineData`. Circle positions, radii, and colors oscillate with a time counter `t`, while lines link adjacent circles and inherit their stroke colors. Running at 60fps via `setInterval`, the example highlights how D3 v7’s `range`, `select`, and join methods handle dynamic, frame-by-frame updates in a React context.

Fork of D3 selections

A dynamic swarm of circles fills the screen, with each circle's position and size oscillating smoothly over time based on a sine wave. The visualization demonstrates D3's data join pattern using `selectAll`, `data`, and `join` to efficiently update the SVG elements every millisecond. Built with React, it uses D3's `range` and custom `makeData` and `vizData` functions to generate coordinates and radii from the current time step. The animation runs continuously via `setInterval`, rendering synchronized, wave-like patterns across the viewport.

Fork of D3 Selection Exploration

This example demonstrates animated circle transitions driven by a continuous data stream. It shows how D3’s data join pattern updates SVG circle positions and radii in real time, with the number of circles and their attributes oscillating sinusoidally. The code uses `d3.select` and `selection.data` with `.join('circle')` to manage enter/update/exit, while `setInterval` triggers a refresh at 60 fps. Data is generated procedurally via `makeData`, which computes varying x, y, and r values based on a time parameter. The visualization highlights the simplicity of binding dynamic data to SVG elements using D3 v6.

Fork of D3 Selection Explorations

A fork of D3 Selection Explorations demonstrates the use of D3's data join and enter/update/exit pattern with animated SVG circles. It uses `d3.select`, `d3.range`, and the `selection.join('circle')` method to bind an array of generated data points to circle elements, updating their positions and radii every animation frame via `setInterval`. The visualization shows a sinusoidal wave of circles moving horizontally and vertically, with the number of circles varying over time as the data array length changes. The code relies on plain SVG rendering without additional libraries beyond D3 v6.

D3 Selection Exploration

This example demonstrates D3’s data join and selection patterns by animating a row of circles whose count and vertical positions oscillate with a sine wave. The code uses `d3.select`, `d3.range`, and `selectAll().data().join()` to update SVG circles at 60 frames per second, while a commented-out version shows the older `enter()`/`merge()`/`exit()` workflow. The visualization renders directly into the browser window via an SVG element sized to `window.innerWidth` and `window.innerHeight`, with no external data source.
