D3 Selection Exploration

D3 Selection Exploration

A grid of ten circles undulates vertically in SVG, their radii and positions governed by sine waves. This animation explores D3's data joins by using `d3.selectAll`, `data`, and `.join('circle')` to bind an array generated with `range` to the circles. The setInterval-driven loop updates positions every 100ms, demonstrating how enter, update, and exit selections work, with the circle count oscillating between five and fifteen.

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.

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.

A set of fifteen circles oscillates vertically in a sine wave pattern, driven by a continuous animation loop. The example demonstrates D3's selection and data-join methods, using `d3.select`, `d3.range`, `selection.data`, `enter`, `merge`, and `exit` to update SVG circle positions every frame. An interval running at 60 frames per second increments a time variable, which modulates each circle's y-coordinate based on its index. The code also includes commented-out alternative using `selection.join`, and renders directly to an SVG canvas sized to the browser window.

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`.

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 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.

A set of circles animates smoothly across the screen, their count and vertical positions oscillating sinusoidally over time. The example demonstrates D3's data join pattern using `selectAll`, `data`, and `.join('circle')` to handle enter, update, and exit states. The SVG is sized to the full viewport, and an interval updates the dataset every 100 milliseconds, repositioning each circle via `attr('cx')` and `attr('cy')`. The source data is generated on the fly with `range` and `Math.sin`, rendering with D3 v6's SVG and animation capabilities.
