Forked from D3 Selection Exploration (Final)

Fifteen circles with dynamically changing radii, positions, and colors pulse in a smooth, endless animation, driven by sine-wave values generated in the `makeData` function. The example uses the D3 library (v7.8.5) with its `select`, `range`, and data-join `join` pattern to render SVG circles directly to the document body. Animation runs via `setInterval` at roughly 60 frames per second, updating a time parameter that alters each circle’s `r`, `cx`, `cy`, and `fill` attributes. The visualization demonstrates real-time data binding and SVG attribute updates with a minimal, dependency-light setup.

D3 Selection animation exercise

Fifteen circles oscillate in a sine wave pattern across the screen, with each circle’s radius enlarging as it descends and shrinks as it rises. The animation runs on a 60fps interval, updating positions based on time and index. Built with D3 v7, it uses `select`, `range`, and `join` to bind freshly generated data to SVG circle elements each frame.

D3 3

Fifteen circles oscillate vertically along a sine-like wave, continuously animating across the screen. The visualization is rendered as SVG elements using the D3 library's selection API. It employs `selectAll`, `data`, and `join` to bind incoming data arrays to circle elements, updating their `cx` and `cy` attributes each frame. A JavaScript `setInterval` timer drives the animation at 60 frames per second, computing new y-positions from a tangent function of the current time step.

Test

An interactive visualization of circles rendered with D3.js, demonstrating the general update pattern and method chaining to bind data to SVG elements. The code uses `select`, `data`, and `join` to create and update circles, with attributes like `cx`, `cy`, `r`, and `fill` set from a hardcoded data array. The SVG element is sized dynamically based on the container dimensions, and circles are drawn with varying positions, radii, colors, and opacity.

D3 selection exploration

Ten animated circles form a sine wave pattern across the screen, with their vertical positions shifting continuously to create a smooth undulating motion. Using D3 v7's `select` and `range` functions, the code binds an array of ten data points to SVG circle elements via the `join` method, updating each circle's `cx` and `cy` attributes every frame at 60 frames per second. The example demonstrates both the data-join pattern and the newer `join` syntax as an alternative to the older `enter`/`merge` approach, with the animation driven by a `setInterval` timer that increments a time variable.

D3 Selection Exploration

Fifteen circles animate vertically in a sine wave across the screen, their positions updating every frame in a loop. Using D3 v6, the code demonstrates the `.join()` method to bind new data arrays to existing SVG circle elements, updating their `cx` and `cy` attributes. The animation runs via `setInterval`, and the source includes commented-out alternative approaches using `.enter()`, `.merge()`, and `.exit()` for comparison.

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.

D3 Selection Exploration

Fifteen circles undulate in an animated sine-wave pattern, with positions and radii oscillating smoothly over time. The example demonstrates D3's selection and data-join mechanics by using `selectAll` and `join` to bind an array of generated data to SVG circle elements. Rendered in SVG, the animation updates every 100 milliseconds via `setInterval`, incrementing a phase variable to drive the motion. The code imports `select` and `range` from D3 v7, showing the modern `join` pattern as a concise replacement for the older `enter`/`merge` approach.

D3 Selection Exploration

Fifteen circles undulate vertically in a sine-wave pattern, creating a rhythmic, animated wave across the browser window. The visualization demonstrates D3's data join and selection methods, where each frame generates new array data and updates the circles' positions. Using `d3.select`, `d3.range`, and the `.join()` pattern, the code binds fresh coordinates to SVG circle elements, which are animated every 60 milliseconds via `setInterval`. Rendering is done in SVG, with circles styled by radius and positioned absolutely by attributes like `cx` and `cy`.
