Two sets of blue and red circles demonstrate a data-join update pattern in D3 v7. Initially, two blue circles render from `data1`. Then, a transition fades those circles out over two seconds, and on completion, four red circles from `data2` fade in using `selection.enter()` and `merge()`. The example uses SVG with `transition.style("fill-opacity", ...)` to animate opacity.

Fade Out Fade In 5

Two blue circles fade out over two seconds, then are removed and replaced by four red circles that fade in at new positions. The example demonstrates a sequential data-update pattern using SVG and D3 v7 transitions. The initial `circ` selection applies a `style("fill-opacity", "0")` transition with its `.on("end", ...)` callback, which calls `.remove()` on all circles before binding the second dataset and entering new circles with a reversed fade-in transition.

Fade Out Fade In 2

Two groups of circles swap places on a D3.js SVG stage: two blue circles fade out and are removed, then four red circles fade in. The example demonstrates a common sequencing pitfall—the new data join executes before the old elements’ removal transition completes, causing selection conflicts. It uses d3.selectAll, data joins, .enter(), and transition().remove() in D3 v7, with fill-opacity transitions timed via .delay() to coordinate the fade-out and fade-in phases.

Fade Out Fade In 4

Four red circles enter in a vertical column while two blue circles fade out and are removed, demonstrating chained selections with overlapping transitions. The example uses D3 v7 with SVG rendering, applying `transition().duration(2000).style("fill-opacity", "0").remove()` to delete the first dataset, then `.on("end", ...)` to append the second dataset. Because the removal and new selection overlap, only three of the four red circles appear, highlighting a timing issue in the transition lifecycle.

Fade Out Fade In

Two sets of circles, first blue then red, fade into and out of view on a blank SVG canvas, appearing sequentially at different coordinates. The visualization uses D3 version 7 to select the SVG element, append circles with an initial opacity of zero, and then chain transitions to animate opacity to one and back to zero. The blue circles fade in over ten seconds, while the red set delays its fade-in by 12.5 seconds before fading out. All circles use a radius of 25 pixels with hardcoded x and y positions from two separate data arrays.

Fork of Fade Out Fade In 2

This example shows two sequential sets of circles. First, two blue circles appear briefly; after two seconds, they fade out and are removed. Then, four red circles fade in, each placed at new coordinates. The visualization uses D3 v7 with SVG and animation. The code demonstrates a common D3 pattern where the `transition()` method applies a fade-out effect, followed by a `.delay(2000)` before the new selection fades in. The author notes the timing issue: the new selection is created before the first circles are fully removed, resulting in only two red circles appearing instead of four.

Fork of Fade Out Fade In 4 - test

Four red circles fade in one by one as two blue circles fade out and are removed from an SVG canvas. The code uses d3 v7 transitions with a `transition.remove()` call and an `on("end")` handler to trigger the second dataset’s entry selection. A conditional checks the index to ensure the callback runs only after the last blue circle’s transition completes. The example demonstrates sequencing data joins and element removal with `selectAll`, `data`, and `enter` methods.

D3 Transitions

Six colored circles float over a pale blue background as D3 transitions animate them into view. Each circle scales from radius zero to its full size with staggered delays, then repositions itself at new coordinates using a faster linear ease. The example uses `selection.join()` to manage enter and update states, applying `transition()` with explicit durations and `easeLinear` to control the motion. Data is defined inline in JavaScript, rendered as SVG circles with distinct fills and 0.667 opacity.

D3 - Transitions

This example demonstrates three ways D3.js handles data updates with transitions. The top SVG updates circles without animation, the middle uses a simple transition to move circles smoothly, and the bottom shows an enter-update-exit pattern where new circles fade in, existing circles move, and removed circles fall downward and disappear. A button click regenerates random data values. The code uses D3 v7 selections, the `.join()` method, and `.transition()` with a duration of 1000ms, all rendered as SVG circles with fill opacity.
