Three SVG circle groups swap positions and sizes in a looping rotation, with circles entering and exiting as the dataset cycles through three IDs. The animation uses D3 v4 selections with keyed data joins, `transition()` for staggered movement, and `attr("r")` to grow new circles from radius zero while shrinking departing ones. The example demonstrates D3’s enter, update, and exit pattern with data-driven `cy` coordinates and a one-second duration, all rendered in animated SVG within a minimal blockbuilder setup.

rotating the circles

Three colored circles continuously rotate through a sequence of colors, shifting left and right in two separate animated containers. One container shows a set of three overlapping circles, while the other displays a single circle that cycles through green, blue, and orange. Using D3 v4’s data joins and transitions, each circle’s size, position, and z-index animate over 400 milliseconds, with the enter and exit selections resizing elements to create a smooth, circular rotation effect.

circles

Three concentric circles rotate continuously around a shared center, with red and green fills determined by radius and blue radial lines indicating rotation. The visualization uses D3 version 6 to append SVG `circle` and `line` elements inside `g` groups, updating their `transform` style via a JavaScript `setInterval` timer. A CSS `@keyframes` animation on hover triggers an additional 360-degree rotation. The code demonstrates D3’s declarative selection and merging API with `d3.select`, `enter`, and `merge` on an SVG canvas sized to viewport dimensions.

transitions

This example animates a set of circles as they move and resize across a wide SVG canvas. Five circles, each driven by values from a static JavaScript array, shift their horizontal, vertical, and radius properties over a four-second duration. The code uses D3's `select()` to append the SVG and builds the animation with the `transition()` API, chaining `.duration()`, `.attr()`, and opacity settings. The circles are rendered as semi-transparent blue shapes, with the initial data divided by a constant factor within the external data module.

D3 Selection Exploration

A set of circles animates smoothly across the screen, their count and vertical positions oscillating sinusoidally over time. The example demonstrates D3's data join pattern using `selectAll`, `data`, and `.join('circle')` to handle enter, update, and exit states. The SVG is sized to the full viewport, and an interval updates the dataset every 100 milliseconds, repositioning each circle via `attr('cx')` and `attr('cy')`. The source data is generated on the fly with `range` and `Math.sin`, rendering with D3 v6's SVG and animation capabilities.

D3 Selection

This example demonstrates animated data-driven circles rendered as SVG elements whose positions, radii, and count oscillate in response to a continuous time variable. It shows how D3’s selection and join API incrementally updates an existing set of circles, adding or removing them as their number changes. The code uses `d3.select`, `selectAll('circle')`, and the `.join()` method to synchronize the SVG with a dynamic array, while a `setInterval` loop recomputes the dataset from trigonometric functions. Circle properties like `cx`, `cy`, and `r` are bound to each datum for smooth motion.

d3js workshop - circles

This example demonstrates how to animate three circles on an SVG canvas using D3.js version 3, showing how data binds to elements and transitions update their appearance. It creates an SVG of 720 by 120 pixels, binds a simple array of three numbers to circle elements, and positions them horizontally based on their data values. The visualization uses chained `transition()` methods with configurable `duration()` and `delay()` to animate the circles’ fill color to red, and also applies radius and vertical position changes. The code relies on D3’s data-join pattern (`selectAll`, `data`, `enter`) and shows how multiple transitions can be sequenced with per-element delays.

D3 Selection Exploration

Fifteen circles animate vertically in a sine wave across the screen, their positions updating every frame in a loop. Using D3 v6, the code demonstrates the `.join()` method to bind new data arrays to existing SVG circle elements, updating their `cx` and `cy` attributes. The animation runs via `setInterval`, and the source includes commented-out alternative approaches using `.enter()`, `.merge()`, and `.exit()` for comparison.

d3js workshop - circles

Three circles are rendered in an SVG, with a red fill and a staggered transition that delays each circle’s color change and radius increase by one second per circle. The example demonstrates D3’s data join, binding an array of numbers to circle positions, and uses `transition().delay()` and `transition().duration()` to animate style and attribute changes over two seconds. The code explicitly appends an SVG element, selects circles via `d3.select`, and applies transitions to fill, radius, and vertical position, showing basic animation and data-driven updates with D3 v3.
