Three circles animate from the top of an SVG canvas to a lower position, changing color from black to red and growing in radius, before a mouseover returns them to their original size and a click shrinks them to nothing. The visualization demonstrates basic D3 data binding and transitions, using `d3.select` to append SVG circles, `selection.data` to bind an array of radius values, and `transition.delay` and `transition.duration` to control the animation timing. Event handlers attached with `selection.on` trigger the mouseover and click responses.

d3js workshop - circles

Three circles, bound to an array of three values, appear in an SVG canvas and animate sequentially: each circle grows, shifts downward, and turns red over two seconds. The code builds the SVG with `d3.select` and `append`, then uses the data-join pattern with `selectAll('circle')`, `data`, and `enter` to create the circles. Mouseover triggers a two-second transition that fills a circle black, while a click transitions it to grey and shrinks its radius to zero, both via `transition.attr` and `style`. The initial animation uses `transition.delay` based on array index.

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.

Three circles of different data values appear in an SVG canvas, then animate by shifting downward and turning red before returning to their original positions on mouseover. The example demonstrates basic D3.v3 selection, data binding, and transition APIs, including `transition().delay().duration()`. Interactive event handling is implemented through `.on("mouseover")`, which changes circle styling and radius. The code initializes an SVG element with `d3.select('body').append('svg')` and uses a data array `[10, 20, 30]` to map circle positions.

Three circles animate sequentially, expanding, turning red, and shifting downward when the page loads. Hovering turns a circle black, while clicking shrinks it to nothing and changes its fill to grey. The example uses D3 v3 with SVG rendering, binding an array of three numbers to circle elements via `data()` and `enter()`. Transitions apply staggered delays and durations through `transition().delay()` and `transition().duration()`, and mouse events trigger additional animated style and attribute changes.

Three circles animate their vertical position and size, turning red before a mouseover returns them to their original state. Built with D3 v3, the example uses an SVG canvas and a simple data array to drive circle coordinates. It demonstrates `selectAll`, chained `.enter()`, and the `transition()` API with `delay` and `duration` for animation, alongside event handling via `.on("mouseover")`. The code is a workshop exercise derived from an interactive circles block.

Three circles render in an SVG across a 720-by-120 canvas, each initially positioned along the x-axis with a fixed radius and vertical center. The example demonstrates D3’s data-join pattern, binding an array of tuples to circle elements and setting their `cx` attributes based on index. A chained transition then animates each circle sequentially, with a one-second delay between starts, over two seconds changing the fill color to the tuple’s second value, increasing the radius to 17, and shifting the y-coordinate to 80. The code uses d3.v3 selection, `.data()`, `.enter()`, `.append()`, and `.transition()` with `.delay()` and `.duration()`.

An interactive D3.js visualization displays three circles that initialize in a horizontal row, then transition to a larger red size with a staggered delay before resetting on mouseover. The example demonstrates basic SVG circle creation using data binding with an array of values, where circle x-coordinates derive from the data. It applies transitions with staged timing and duration, then adds mouseover events to change circle fill color and dimensions, returning them to their original state. The code uses d3.select, selection.data, enter, append, transition, and event handling.

Three circles spaced horizontally transition in sequence from their initial position, turning red as they shift downward. Hovering reverses the effect, returning a circle to its starting point in black; clicking turns it green, briefly enlarges it, then shrinks it to nothing. The example demonstrates D3 data joins, selection, and event handling within an SVG scene, using D3 v3’s `transition()`, `delay()`, `duration()`, and `on()` methods on a fixed data array. It extends a basic circles tutorial with interactive feedback and animated state changes.
