Fifteen yellow circles animate in a sine-wave pattern across a black canvas, with their vertical position, radius, and opacity oscillating over time. The visualization demonstrates declarative selection and joins in d3 v7.8.5's `select`, `range`, and `.join` methods within a React framework, rendering SVG elements and updating them on a 100-millisecond interval using `setInterval`. The code manipulates circle attributes such as `cx`, `cy`, `r`, `fill`, and `opacity` directly through chained `.attr` calls.

D3 Selection Exploration

Fifteen circles animate in a wave-like pattern across an SVG canvas, their vertical positions oscillating sinusoidally over time. The visualization demonstrates D3's data-join pattern using `selectAll`, `data`, and `join` to bind an array of generated objects to circle elements, updating their `cx` and `cy` attributes every 100 milliseconds via `setInterval`. The example uses `d3.range` to create the dataset and the `select` function from the D3 v7 library, rendering purely with SVG and a React-compatible setup.

D3 Selections

Two hundred blue circles form a sine wave that continuously animates across the screen, with each circle’s vertical position shifting based on a time-driven formula. The visualization demonstrates D3’s data join pattern using `selectAll`, `data`, and the `.join()` API to efficiently update existing SVG circle elements rather than recreating them. The example runs in a React framework with SVG rendering, updating every 16 milliseconds via a JavaScript `setInterval` timer, and pulls data from a procedurally generated range of 200 points.

D3 Selection Exploration

D3 Selection Exploration demonstrates animated data binding and joins with D3 v7. It renders 15 circles and corresponding lines on an SVG canvas, with positions and radii oscillating sinusoidally over time via a `setInterval` loop. The code uses `select`, `range`, and the `.join()` method to handle enter, update, and exit selections for both `circle` and `line` elements, updating coordinates (`cx`, `cy`, `x1`, `y1`, `x2`, `y2`) each frame.

D3 Selections

An animated SVG demonstrates the D3 selection API by updating a set of circles. The visualization shows fifteen circles moving in a sine wave pattern, with their vertical position oscillating over time. The code uses D3’s `select` to target the body element, `range` to generate data, and a `join` operation to efficiently update existing circles based on the incoming data. The animation runs at 60 frames per second via `setInterval`, creating a smooth, continuous motion. The example highlights the workflow of selecting, appending, and merging SVG elements with D3’s data-binding methods.

D3 Selection Exploration

A set of 15 circles animates in a sine-wave pattern across the browser window, with each circle's vertical position and radius oscillating over time. The code uses D3 v6's `select`, `range`, and `data` join methods to bind an array of computed objects to SVG circle elements. A `setInterval` at roughly 60 frames per second updates the data and re-renders via the `.join('circle')` pattern, which handles enter, update, and exit states seamlessly.

D3 Selection Exploration

A dynamic collection of circles animates in real time, with positions, radii, and colors shifting continuously. The visualization demonstrates React and D3 version 7 selection methods, using `select` and `join` to bind and update SVG circle elements to arrays of data objects generated by a custom `makeData` function. An interval drives the animation at roughly 60 frames per second, incrementing a time variable that modulates sine waves controlling each circle's vertical position, radius, and RGB color values. The example showcases how D3's data joins efficiently handle live updates to the DOM.

D3 Selection Exploration

A dynamic set of circles animates across the screen, with positions and radii fluctuating sinusoidally over time. The visualization demonstrates D3's data join pattern, where an SVG selection binds to an array of generated points and updates each frame. Using `select` and `join`, the code continuously enters, updates, and exits circle elements based on data from `makeData`. The interval-driven animation synchronizes circle movement and sizing, showcasing D3 v6 selection methods within a React-compatible structure.

D3 selection exploration

This example explores D3 selections and data joins through an animated visualization. A sinusoidal wave of circles moves across the screen, with the number of circles oscillating based on a time variable. The code uses d3.select and d3.range to generate data, then applies the selection’s `.data()`, `.join()`, and attribute setters to update SVG circle positions each frame. The animation runs via `setInterval` at 60fps, with sine functions driving both the vertical placement and count of circles, demonstrating enter, update, and exit behavior.
