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.

D3 Selection Exploration

This example demonstrates dynamic D3 selection and data binding by animating a set of circles that move and resize in a sine-wave pattern. Using `d3.select`, `selection.data`, and `.join`, it updates the SVG circle positions and radii every frame at 60fps via `setInterval`. The `makeData` function generates the x, y, and r values, while the `vizData` module applies the attributes. Rendering relies on SVG elements with no transitions, showing raw join behavior. The data is synthetic, derived from trigonometric functions, and the visualization fills the browser window.

D3 Selections Explorations

This example demonstrates dynamic data binding in D3.js, showing a group of circles that smoothly oscillates in count and position to create a flowing wave-like pattern. Using D3 selections and the `join('circle')` method, it updates the SVG in real time, while a `setInterval` callback runs at 60 frames per second. The code leverages `d3.range` to generate data points and animates their x and y coordinates based on trigonometric functions of a time variable. The visualization is rendered entirely with SVG elements in an HTML page.

D3 Selection Explorations

A collection of animated circles demonstrates D3's data-join pattern for dynamic SVG rendering. The visualization continually updates data via a JavaScript interval, adjusting the number and positions of circles based on sine waves. Using D3 v6, the code employs `select`, `range`, and the `join` method to bind new data to existing SVG circle elements, updating their `cx` and `cy` attributes at 60 frames per second. The example highlights the simplicity of enter, update, and exit handling within a single chained call.

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 Exploration

This example demonstrates a dynamic animation of fifteen circles moving in a sinusoidal wave pattern across the screen, with each circle’s vertical position updated continuously. The visualization uses the D3.js library (version 6.6.2), specifically leveraging the `select`, `range`, and `join` APIs to manage the SVG elements. The code generates data points calculated from a time variable, then updates the circles’ `cx` and `cy` attributes at a fixed 60-frame-per-second interval using `setInterval`. The rendering is SVG-based, with a live animation that replays the wave motion indefinitely.

D3 Selection Exploration

This example demonstrates animated data binding in D3.js, showing how SVG circles are dynamically added, removed, and updated as the dataset changes in real time. The visualization uses D3's `selectAll` and `join` methods within a custom `vizData` function to manage circle elements, while a `setInterval` loop drives the animation at 60 frames per second. Data is generated procedurally using `d3.range` and `scaleLinear`, with each circle's position and radius varying based on sine functions of time and index. The source code imports from the D3 v6 module and renders directly to an SVG canvas in the browser.

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.

D3 Selection Exploration

A dynamic SVG animation demonstrates D3's data join pattern with shifting circle counts. The visualization uses `d3.select`, `d3.range`, and the `selection.join()` method to bind an array of computed data points to circle elements, updating their `cx` and `cy` attributes with sine-based positions. Circles appear and disappear as the data length varies, driven by a `setInterval` callback that increments a time variable at 60 frames per second. The example renders directly into the browser using D3 v6, with no external data source beyond the generated numeric values.
