A sequence of blue circles enters, shifts to green, and updates to orange as the dataset grows and shrinks over time; circles removed from the data turn red before disappearing. This animation demonstrates how D3 v5’s `selectAll`, `exit`, and `enter` selections handle data changes, using svg transitions with a 700-millisecond duration for updates and 500-millisecond for exits. The underlying data is a simple array of x-coordinates, rendered as SVG circles with a fixed y-coordinate and radius, driven by timed `render` calls in a static HTML page.

Fork of Template Enter, exit and update

A D3.js animation demonstrates how enter, update, and exit selections handle changing data. Six blue circles appear in a row, then one circle is removed after two seconds, and the first remaining circle turns red after four seconds. The code uses `selection.selectAll`, `.data()`, `.enter()`, `.exit()`, and `.transition()` from D3 v7, with `scaleOrdinal` mapping types to colors. SVG elements are rendered and animated directly on a blank canvas.

Enter, Exit, Update

This example demonstrates the enter, update, and exit phases of D3’s data-join process using three selectable buttons that swap between different arrays of named values. Each array’s items are rendered as circles, showing how new items appear, existing items change position, and removed items shrink away. The visualization uses D3 v4’s `.data()`, `.enter()`, `.exit()`, and `.merge()` methods alongside the `.transition()` API for smooth animations. The SVG circle’s fill color is mapped to each item’s `id`, while the x-coordinate is derived from its index in the current array.

D3 Selection Exploration (Enter - Update Selections Clearly Separated)

This example demonstrates the D3 enter-update pattern by animating a set of fifteen circles along a sine wave. Every five seconds, the data array is regenerated, and the code clearly separates the enter selection—which appends new circles with `circles.enter().append('circle')`—from the update selection that repositions existing elements via `circles.attr('cx', ...)` and `circles.attr('cy', ...)`. Using D3 v7 with SVG, the visualization shows how identical data keys map to existing nodes, avoiding duplication. The animation loops indefinitely using `setInterval`, and the rendering adjusts to the full browser window size.

Fork of Template Enter, exit and update

This example demonstrates the D3.js enter, update, and exit pattern using animated SVG circles. Six circles initially appear, then one is removed after two seconds, and the first circle changes color after four seconds, with each state change triggering a two-second transition. The visualization uses `d3.select`, `d3.range`, `d3.scaleOrdinal`, and `transition()` to illustrate how data joins and lifecycle methods handle dynamic updates. The color scale maps object types to fill colors, though the initial and updated object types are not explicitly defined in the code.

Exit, Update, Enter

Three divs demonstrate D3's enter-update-exit pattern with staggered transitions. An existing "update" and "exit" element bind to new data, turning the update orange while the exit fades red and removes itself. A new "enter" element fades in green after a delay. The example uses D3 v3's `selection.data`, `transition.delay`, and `style` to chain animations, with explicit delay calculations based on whether exit and enter selections are empty.

Presentation Enter, exit and update

Six circles, initially red and arranged horizontally, demonstrate the D3 enter, update, and exit lifecycle. The animation updates the data array and re-renders: after two seconds, one circle is removed via `exit().remove()`, and after four seconds, the first circle updates from type 'A' to 'B', changing its fill color through a 2-second `transition()`. The SVG renderer uses `d3.scaleOrdinal` for color mapping.

D3 Transitions

Six colored circles enter, update, and exit the screen using animated D3 transitions. The initial enter animation scales each circle from a radius of zero to its target size with a staggered delay, while the update transition moves circles to new positions quickly and the exit transition shrinks them back to nothing before removal. The example demonstrates the `selection.join()` pattern with separate enter, update, and exit handlers, using `transition().duration()` and `easeLinear` from D3 v7 to control timing and motion on an SVG canvas.

Fork of Template Enter, exit and update

This example visualizes 60 green circles arranged diagonally across an SVG canvas, each positioned at increasing x-coordinates and decreasing y-coordinates. The circles are created using D3 v7’s enter selection, where `selection.selectAll('circle')` binds the array of objects to new circle elements. A `scaleOrdinal` color scale maps all objects to a single green color. The code demonstrates the fundamental data-join pattern, though it does not include exit or update transitions despite the title referencing them.
