A wave of circles moves across the screen, oscillating vertically in a sine-like pattern as their count fluctuates over time. The animation uses D3’s data join to update SVG circle elements on a 60-frame-per-second interval, with `selectAll`, `data`, and `join` binding new arrays generated from `range` and trigonometric functions. The number of circles changes dynamically based on a time variable, while each circle’s position is recalculated from its index and the current time step.

JavaScript Arrays

Animated circles move in sine-wave patterns across the screen, with their count oscillating as the wave amplitude changes. The visualization demonstrates dynamic data binding in D3 v6, using `selectAll` and the `join` method to update SVG circle elements each frame. A `setInterval` drives the animation, generating data arrays with `d3.range` and updating circle positions via `.attr`. The example highlights how D3 handles enter, update, and exit states through the join pattern, creating a fluid, generative animation.

A row of circles animates continuously, with each circle bobbing vertically and pulsing in radius as the total count fluctuates between five and fifteen. The example demonstrates dynamic data joins in D3.js 7, using `d3.select`, `d3.range`, and `selection.join` to bind and update SVG circle elements at 60 frames per second. A sine-wave based `setInterval` loop drives the positions, radii, and count, rendering directly to an SVG canvas sized to the browser window.

This example animates a dynamic set of circles whose positions oscillate vertically based on a sine wave, creating a flowing wave-like pattern across the screen. It demonstrates D3’s data join pattern using `selectAll`, `data`, `enter`, `merge`, and `exit` to add and remove circles as the dataset size changes over time with `range` and `Math.sin`. The visualization uses D3 v7 in a React-less HTML setup, rendering to SVG on a full-window canvas, with `setInterval` driving the animation at 60 frames per second.

An animated scatter of sine-driven circles demonstrates D3’s data join with `selection.join`. The number of circles oscillates as the array length changes, while each circle’s x-position increments by 50 pixels and the y-position follows a sine wave. The SVG viewport resizes to the window, and the animation updates every 10 milliseconds. Using `d3.range` and `Math.sin`, the code smoothly re-enters, updates, and exits circles, showcasing D3 v3’s reactive data binding and the concise `join` API.

This example visualizes a dynamic sine wave as a shifting field of circles, whose count and vertical positions oscillate continuously over time. Built with React and rendered as animated SVG, it uses D3’s `select`, `range`, and data join (`join('circle')`) to update circle positions every 10 milliseconds based on a time variable. The number of circles fluctuates between 0 and 200, while each circle’s y-coordinate follows a sine function that creates a flowing, wave-like motion across the screen.

Animated circles undulate across the screen, their positions and radii shifting smoothly with a sinusoidal rhythm to illustrate dynamic array manipulation in JavaScript. The visualization uses D3.js (v7) with SVG rendering, generating data through a custom `makeData` function and updating the scene at 60 frames per second via `setInterval`. The D3 join pattern in `vizData` binds new data arrays to existing circle elements.

D3-Arrays

Fifteen black circles undulate in a vertical sine-wave pattern across a full-screen SVG. Each circle updates its vertical position based on a time-incremented angular offset, creating a smooth, animated wave. The example uses D3 v7's `select`, `range`, and `symbol` APIs, with a JavaScript `setInterval` driving the animation loop. Data is generated on the fly as an array of position objects, bound to circle elements via D3's data join, while SVG attributes are updated each tick.

This example animates a sequence of 15 circles whose vertical positions and radii oscillate over time, creating a fluid wave-like motion. The circles are generated procedurally using sine functions, with each frame updating their `cx`, `cy`, and `r` attributes. The visualization uses D3.js v6 and its `select`, `range`, and `join` APIs to render the dynamic scene as an SVG, with an animation loop driven by `setInterval`. The data is recalculated in `makeData` and passed to `vizData` via the `svg.call` method.
