D3 Selection Exploration

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.

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`.

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 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 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.

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.

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.
