Forked from arrays

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

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 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 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 how D3 selections manage dynamic data updates through animation. An SVG scene continuously redraws a set of circles and connecting lines, with the number of elements oscillating between 5 and 15 based on a sine wave. The code uses D3’s `select` and `range` functions, along with the `join` pattern to bind data to circle and line elements. Data is generated procedurally via `makeData`, updating positions and radii each frame. React serves as the framework wrapper, while the animation runs on a `setInterval` timer with a 60fps approximation.

D3 selection exploration

This example demonstrates how D3’s data join and selection mechanism dynamically updates an SVG scene in real time. An animated set of circles shifts vertically based on a sine wave, with their count oscillating between five and fifteen as time progresses. The code uses `d3.select`, `d3.range`, and `.join('circle')` to bind incoming data to SVG elements, updating positions each frame via `setInterval`. Data is generated procedurally from a mathematical function rather than an external dataset.

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 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 and Exploration

A collection of animated circles moves across the screen, their positions and sizes oscillating in a wave-like pattern over time. The visualization demonstrates dynamic data binding and updates in D3 v7, using `select`, `range`, and the `.join()` method to create and modify SVG circle elements at 60 frames per second. The animation is driven by `setInterval`, recalculating each circle's x-coordinate, y-coordinate, and radius based on sine functions that incorporate a continuously incrementing time variable.
