Three circles animate from the top of an SVG canvas, shifting downward and turning red through a D3 transition, then revert to their original position and black fill on mouseover. Clicking a circle sets its radius to zero, removing it from view. The example uses D3 v3’s selection, data binding, and transition methods, with event handlers for mouseover and click. It renders with SVG elements and demonstrates basic interactivity, showing how D3 binds an array of numbers to visual properties like x-position and radius.

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.

d3js workshop - circles 2

This example demonstrates three circles that animate and respond to user interaction. The circles initially appear at set positions, then transition to a new radius and vertical offset before returning to their original state on mouseover. A click event is also set up to shrink a circle out of existence. The visualization uses D3.js v3, selecting SVG elements and binding data to create the circles, with transitions controlling the animated changes and event listeners handling mouseover and click actions.

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.

Intro D3 Workshop

Fifty red circles radiate from the center of an SVG canvas, each sized by a random count value and positioned by distance from a clicked circle. Clicking a circle increments its count and re-renders the layout, animating all circles to new positions via `transition()` over 800 milliseconds. The example uses D3 v4 scales (`d3.scaleSqrt`, `d3.scaleLinear`) to map counts to circle radius and color, with a color gradient from steelblue to red based on proximity to the clicked circle. A gray ring backdrop and trigonometric positioning complete the interactive workshop demo.

Fifty red circles orbit a central point, each sized by a random count and positioned by its similarity to a clicked circle. Clicking a circle moves it to the center, increments its count, and reseats all points by a distance function. The example demonstrates animated transitions with d3.scaleLinear for radius and color, d3.scaleSqrt for size, and SVG circle elements, using a click handler and transition duration of 800ms.

D3 Workshop: Part 2 - SVGs and d3 Transitions

This example demonstrates how to animate SVG elements with D3 v4, showing a static red circle and blue rectangle alongside small rectangles that jump to random positions and colors when a button is clicked. It illustrates data joins by binding an array of color objects to newly appended rectangles, then transitions them with `d3.transition()`. A `setInterval` loop continuously updates the rectangles' positions and fills using random values from the data array, while the initial static shapes remain unchanged. The code uses `selection.enter()`, `merge()`, and chained `.attr()` and `.style()` methods for smooth animations.

Three circles—green, blue, and red—sit in a row on a gray SVG canvas. Clicking a rectangle starts a two-second animated transition that moves the red circle diagonally downward, followed by a second transition returning it horizontally. The red circle also turns black on mouseover, while the green circle responds to hover via a CSS class. Built with D3 v5, the example demonstrates selections, event handlers, and chained `transition.attr` calls, with no external data source.

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.
