Five squares and circles, created from a d3.range array, transition as new groups are entered when the data array expands from five to ten elements. The example demonstrates the d3 v4 enter and merge pattern, using `selection.enter().append()` to add new SVG groups and `selection.merge()` to update existing ones. Shapes animate via `transition()` with staggered delays based on index, while `redraw()` is called twice with different sizes, showing how enter selections handle varying data lengths.

groups - transitions

The example demonstrates D3.js data joins with entering, updating, and exiting groups of fruit shapes, rendered as SVG circles and text labels. It animates state changes over time via `setTimeout`, including swapping fruit types and removing items from the array. The code uses `scaleOrdinal` for color and radius mappings, and merges enter and update selections with `selection.merge`. The fruit data is generated randomly and rendered inside a static brown bowl rectangle.

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.

D3.js - join() with enter, update, and exit

This example demonstrates D3.js’s `join()` method by binding an array of numbers to SVG circles, with buttons to prepend, append, or drop data items. Entering circles animate their radius from zero and color to hotpink via `transition.attr`, while updated circles shift horizontally and exiting circles shrink to zero before removal. The code uses a key function `(d) => d` for datum identity, `d3.selectAll`, `.data()`, and `.join()` with separate enter, update, and exit handling. Rendering uses SVG and transitions with 500-millisecond durations.

Enter, Exit, Update (i.e Merge)

This example demonstrates D3’s enter, exit, and update pattern for binding data to SVG rectangles, showing how bars are added, resized, or removed as the dataset changes. The code uses `selection.enter()`, `.merge(selection)`, and `selection.exit().remove()` within a reusable `drawChart` function, and it calls that function twice with different data arrays to illustrate the transitions. It relies on the D3 v5 `select` and `merge` APIs, with SVG rendering in a fixed 960×500 viewport.

Enter append etc

Two interactive rectangles act as buttons for updating a data-driven circle chart in D3.js. The example demonstrates the enter and append pattern, where clicking `rect1` replaces the dataset with a new array of three values, and clicking `rect2` adds two additional circles. Initially, three circles are rendered with radii proportional to the square root of the data values. The code uses `d3.selectAll("circle").data()` and `.enter().append()` to create new SVG circle elements, with transitions animating the radius updates.

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 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.

Update and Enter - Another Take

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.
