D3 selection

This example demonstrates a dynamic field of circles that continuously undulate across the screen, their positions and radii shifting over time. It displays a swarm of shapes moving in a wave-like pattern, driven by a sine function of time and index. The visualization uses the D3.js library’s `select` and `range` APIs to manage SVG elements, appending a full-screen SVG canvas. Through an animation loop using `setInterval`, it regenerates data at 60 frames per second, employing `selectAll` and `join` to efficiently update the existing circles’ attributes, creating a smooth, organic motion.

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

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.

Select D3 L4

A set of circles animates in a sine-wave pattern across the screen, with each circle’s vertical position and radius fluctuating over time. The visualization uses D3’s `select` and `range` functions to generate data and bind it to SVG circle elements via `join`. A `setInterval` loop updates the data every 60th of a second, recalculating each circle’s `cx`, `cy`, and `r` attributes based on a changing time variable. The animation runs continuously, creating an organic, flowing motion.

selecting

This example demonstrates animated data visualization using the D3.js library (version 7). It shows a dynamic set of circles that move vertically and change radius over time, with the number of circles oscillating between 15 and 25. The visualization uses `d3.select` to target the SVG container, `d3.range` to generate data points, and a custom `vizData` function that employs `selection.selectAll` and the `.join` method to efficiently handle entering and updating circle elements. The animation runs at 60 frames per second via `setInterval`, updating positions based on a sine wave function.

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`.

D3 Selections

An animated SVG demonstrates the D3 selection API by updating a set of circles. The visualization shows fifteen circles moving in a sine wave pattern, with their vertical position oscillating over time. The code uses D3’s `select` to target the body element, `range` to generate data, and a `join` operation to efficiently update existing circles based on the incoming data. The animation runs at 60 frames per second via `setInterval`, creating a smooth, continuous motion. The example highlights the workflow of selecting, appending, and merging SVG elements with D3’s data-binding methods.

D3 Selections

This example animates a set of circles and vertical lines in an SVG, with the circles bobbing up and down in a sine wave pattern over time. The visualization uses D3’s `select`, `append`, and `selectAll` APIs to manage the SVG elements, and the `join` method to update the DOM as new data arrays are generated each frame by `makeData`. The animation is driven by a `setInterval` timer that updates the data and redraws the scene at 60 frames per second, with line opacity varying based on the circle’s vertical position.
