This example demonstrates D3’s data-join and selection patterns by animating a variable number of circles across the screen. It uses `d3.select`, `d3.range`, and the `data()`, `.join()`, and `attr()` methods to bind an array of objects with computed `x` and `y` positions—derived from sine waves—to SVG `<circle>` elements, updating every frame via `setInterval`. The number of circles oscillates between 5 and 15, and the `.join()` method handles enter, update, and exit seamlessly. The visualization runs in a React-free HTML page with a minimal SVG canvas sized to the window.

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.

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 Selection exploration

This example demonstrates D3 selection and data-join patterns by animating a series of circles and connecting lines across a full-screen SVG. As time progresses, the circles oscillate vertically along sine waves while lines link consecutive points. The code uses `d3.select`, `d3.range`, and the `selection.join` method to bind and update elements each frame. Rendering is driven by a `setInterval` loop that regenerates the data and re-applies the `makeCircle` and `makeLine` functions, highlighting how D3 manages enter, update, and exit states.

D3 Selection Exploration

This example demonstrates how D3’s data join pattern animates a dynamic set of circles, whose count and vertical positions oscillate sinusoidally over time. Using `d3.select` and `d3.range`, it generates an array of points and binds them to SVG circle elements via `selection.data()` and `selection.join()`, updating `cx` and `cy` attributes each frame. The code runs a `setInterval` at 60fps, recalculating data with a time-based sine wave, while `d3` version 7.6.1 manages enter, update, and exit states automatically.

D3 Selection Exploration

This example demonstrates D3’s data join and selection patterns by animating a row of circles whose count and vertical positions oscillate with a sine wave. The code uses `d3.select`, `d3.range`, and `selectAll().data().join()` to update SVG circles at 60 frames per second, while a commented-out version shows the older `enter()`/`merge()`/`exit()` workflow. The visualization renders directly into the browser window via an SVG element sized to `window.innerWidth` and `window.innerHeight`, with no external data source.

D3 Selection Exploration

This example demonstrates D3’s selection and data-join mechanisms by animating a set of circles whose count, positions, and radii oscillate over time. It renders in SVG, updating every frame via `setInterval`, and uses `d3.select`, `d3.range`, and the `selection.join()` method to bind changing array data to circle elements. The motion follows sine waves, producing a rhythmic, fluid visual. The code relies on D3 v6, with no external data source or interaction.

D3 selection exploration

This example demonstrates animated selection and data-join techniques in D3, showing fifteen circles bobbing vertically in a sine-wave pattern across the screen. The visualization uses d3.select and d3.range to generate data, then applies the .join('circle') method to bind that data to SVG elements. A setInterval loop running at 60 frames per second updates the circles’ cx and cy attributes, with the y-position calculated from a sine function of the data index and a time variable t. The animation relies entirely on d3 v7’s selection methods and SVG rendering.

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.
