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.

A set of animated circles undulates across the screen, their vertical positions and radii oscillating sinusoidally with a slowly changing phase. The visualization demonstrates data joins in D3 v6, using `selectAll`, `data`, and `join` to update SVG circle elements every frame via `setInterval`. Generated data from `makeData` feeds the `vizData` function, which binds new values for `cx`, `cy`, and `r` at 60 frames per second.

A set of fifteen circles moves in a vertical sine wave, with each circle's radius also oscillating in sync. The circles are connected by a black line, forming a continuously undulating path. The animation updates every 100 milliseconds by generating new data with `d3.range` and trigonometric functions in `makeData.js`. The rendering uses D3's `select` and `join` operations within `vizData.js` to handle enter and update selections, appending SVG `circle` and `path` elements to the page.

This example animates a set of circles moving in a horizontal wave pattern across the screen. The number of circles changes over time, increasing and decreasing in response to a sine function. Built with D3 v6, the visualization updates at roughly 60 frames per second using `setInterval`, joining new data with `selection.join` to create and position the SVG circles. The `range` and `select` APIs generate the data and manage the DOM.

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.

This example demonstrates dynamic SVG circle generation and animation using D3 v7. An array of circles, generated from a sine-based function, continuously updates position and radius to create a flowing wave effect. The code uses D3's `select`, `selectAll`, `data`, and `join` methods to bind new data and manage enter/update/exit cycles. An interval-driven animation loop calls `vizData` at 60 frames per second, with data created by `makeData` using D3's `range` utility. The visualization runs in an HTML page with no external data sources.

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.

Two hundred blue circles form a sine wave that continuously animates across the screen, with each circle’s vertical position shifting based on a time-driven formula. The visualization demonstrates D3’s data join pattern using `selectAll`, `data`, and the `.join()` API to efficiently update existing SVG circle elements rather than recreating them. The example runs in a React framework with SVG rendering, updating every 16 milliseconds via a JavaScript `setInterval` timer, and pulls data from a procedurally generated range of 200 points.
