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

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 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

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

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

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.

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.
