Two datasets of varying circle sizes and counts are displayed along a horizontal axis. A button click uses `d3.select` and event listeners to toggle between datasets, demonstrating D3’s data join pattern with `data()`, `enter()`, and `exit()`. New circles appear via `append` with an initial radius of zero, while all circles transition with `transition().duration(500)` to update their `cx` and `r` attributes, and the dataset label changes via `select("text").text()`. The SVG elements are rendered as orange, semi-transparent circles.

Changing data

An interactive chart uses D3 to display circles representing two datasets. Clicking a button switches between datasets, triggering D3 transitions that animate the circles to their new positions and radii. The SVG rendering uses D3’s selection, data joins, enter/exit, and transition API to smoothly update the visualization, with a text label that updates accordingly.

D3 functions

This example demonstrates D3’s data-join pattern with a set of circles plotted on an SVG canvas. Buttons trigger updates: “Remove” pops a data point, while “Modify” replaces a random point with new coordinates. Using `selectAll('circle')`, `enter`, `merge`, and `exit`, it shows how to handle entering, updating, and exiting elements. The code uses D3 v5’s `scaleLinear`, `select`, and `max`, with data defined as an array of `{x, y}` objects and rendering via SVG circles.

d3js - enter(), update() and exit()

A bar of five orange circles sits along a horizontal axis, with a button to swap between two data arrays of different lengths. Using D3 v3, the example demonstrates the data-join pattern: `enter()` appends new circle elements when longer data arrives, `exit()` removes surplus circles when data shrinks, and a `.transition()` updates all remaining circles’ radii and positions. The axis is drawn as simple SVG `line` elements with `text` labels, and the dataset label updates with each toggle.

This example shows how D3.js can animate transitions between two different datasets, displayed as orange circles along a horizontal axis. The circles’ radii and horizontal spacing are derived from each dataset’s values, and a button toggles between the two arrays. The implementation uses `transition()` to animate the circles’ `cx`, `cy`, and `r` attributes over 500 milliseconds. The code relies on D3’s selection and `.enter()`/`.exit()` methods to add or remove circles when the dataset changes, with SVG elements for rendering.

Five circles sit on a shared horizontal axis, each sized by a value from the current dataset. A button switches between two data arrays, triggering a one-second transition that repositions circle radii and x-coordinates. Using D3.js v6 with SVG and animation, the code employs data joins, `enter`/`exit` selections, and `transition` to update the visualization. An axis line and a title label (highlighting the active dataset) complete the chart, which renders entirely in the browser.

D3 Selection

This example demonstrates animated data-driven circles rendered as SVG elements whose positions, radii, and count oscillate in response to a continuous time variable. It shows how D3’s selection and join API incrementally updates an existing set of circles, adding or removing them as their number changes. The code uses `d3.select`, `selectAll('circle')`, and the `.join()` method to synchronize the SVG with a dynamic array, while a `setInterval` loop recomputes the dataset from trigonometric functions. Circle properties like `cx`, `cy`, and `r` are bound to each datum for smooth motion.

D3 Selection Exploration

A set of circles animates smoothly across the screen, their count and vertical positions oscillating sinusoidally over time. The example demonstrates D3's data join pattern using `selectAll`, `data`, and `.join('circle')` to handle enter, update, and exit states. The SVG is sized to the full viewport, and an interval updates the dataset every 100 milliseconds, repositioning each circle via `attr('cx')` and `attr('cy')`. The source data is generated on the fly with `range` and `Math.sin`, rendering with D3 v6's SVG and animation capabilities.

D3 Join Exploration 2

This example demonstrates real-time animated data joins in a browser window. It uses D3’s `select` API to create an SVG canvas and repeatedly updates a dataset of circles via `setInterval`. The code explicitly exercises the `.join('circle')` method to bind new data to existing SVG circle elements, transitioning their `cx`, `cy`, and `r` attributes based on a sine wave function. The visualization shows smooth, continuous motion of circles while also varying their count (from 5 to 15) over time, all rendered as vector shapes. D3’s `range` utility generates the underlying numeric sequence for the dataset.
