This example demonstrates a looping transition animation in d3.js v7. A single steel-blue circle moves horizontally across an SVG canvas, traveling from the left edge to the right and back again. The animation uses the `d3.transition` API, chaining two successive `.transition()` calls with a duration of 2000 milliseconds each. Upon completing the return trip, an `.on("end", repeat)` callback triggers the entire sequence to start over, creating an infinite loop. The circle’s position is set via the `cx` and `cy` attributes.

AI-generated description

This is a demonstration of looping transition chaining using d3.js v7.

The circle moves from left to right and then back again so that it starts and ends in the same state and then we instruct the transition code to repeat itself.

This graph is part of the code samples for the update to the book D3 Tips and Tricks to version 7 of d3.js.

Looping a transition in v5

This example demonstrates a looping transition in which a steelblue circle travels from the left side of an SVG canvas to the right and back again, repeating indefinitely. It shows how to chain two sequential transitions on the same element by using the `transition` API from d3-transition, with the `.duration()` method controlling the 2000-millisecond timing for each leg. The circle’s position is set with `.attr('cx', ...)` and `.attr('cy', ...)`, and the `on("end", repeat)` callback restarts the entire sequence, creating seamless motion across the 960×500 viewport.

Looping a transition in v6

A single steelblue circle loops a transition chain across a 960-by-500 SVG canvas in D3 v6. A custom `circleTransition` function appends the circle, then chains `.transition()` calls with `.duration(2000)` to move it from x-coordinate 40 to 920 and back. The `.on("end", repeat)` callback restarts the same chained movement, creating an infinite back-and-forth animation. This example demonstrates transition chaining and callback-driven repetition using d3-transition.

Looping a transition in v4

A steelblue circle loops horizontally across a 960-pixel-wide SVG canvas, moving right for two seconds and then left for two seconds in a continuous cycle. The example demonstrates d3-transition chaining in d3.v4 using `.transition()` and `.duration()` to animate the `cx` attribute, with the `on("end")` event triggering the repeat function. This serves as a starting template for building more complex looping animations in D3 version 4.

Simple transition in v7

A blue circle transitions horizontally across a wide SVG canvas in this minimal demonstration of d3-transition. The circle moves from the left edge to the right over four seconds, using a chained `transition()` with a `duration(4000)` call after initial attributes are set. The example uses d3.v7 to select the body, append an SVG element, and define the circle’s fill, radius, and starting coordinates before applying the animation. No data source is involved; the code directly specifies all visual properties and the animation target position.

Simple transition chaining in v7

This example uses chained `transition()` calls in d3.v7 to animate a single SVG circle through three sequential stages. The circle first slides horizontally from left to right, then expands its radius, and finally changes its fill color from blue to red, with each transition lasting 4000 milliseconds. The animation is built entirely with D3’s selection and transition API, applying attributes like `cx`, `r`, and `style` through `.attr()` and `.style()` methods. The code appends the circle directly to the body via an SVG element, with no external data source.

Simple transition in v6

A blue circle moves horizontally across an SVG canvas, demonstrating a simple transition in d3.js v6. The code appends a circle to the body, sets its initial position and fill, then uses the `transition()` method with a `duration` of 4000 milliseconds to animate the `cx` attribute from 40 to 920 pixels. This example illustrates the basic syntax for chaining a transition onto a selection to animate SVG attribute changes.

Simple transition chaining in v6

A circle demonstrates sequential transition chaining in d3.js v6, moving from left to right, then expanding its radius, and finally changing fill color from blue to red. Using the d3-transition API, the code applies three consecutive `.transition()` calls, each with a 4000-millisecond duration, to an SVG circle appended to the body. The example shows how transitions queue and execute in order, rendering the animation directly in SVG.

Simple transition chaining in v5

A blue circle moves across an SVG canvas in three sequential transitions, each lasting four seconds. First, its horizontal position animates from the left side to the right side; then its radius grows from 20 to 40 pixels; finally, its fill color changes from blue to red. This example demonstrates transition chaining in D3 v5, where calling `.transition()` after a previous transition schedules the next animation to begin automatically. It uses D3’s `transition` API with `.duration()` and `.attr()`/`.style()` methods.
