This example demonstrates data joins in D3 by animating a set of circles based on sine functions, with both the count and positions updating continuously. Drawn as SVG elements, it highlights the difference between the pre-v6 enter/merge/exit pattern and the modern `.join()` shorthand for binding data. The animation runs on a 60fps interval, using `select`, `range`, and chained attribute setters to update circle radius, x, and y coordinates in real time.

D3 Selection Exploration

This example demonstrates D3 data joins with animated circles that continuously update position and radius. It uses D3 v6’s `select`, `range`, `scaleLinear`, and the `.join('circle')` pattern to bind new data each frame. The `setInterval` drives a 60fps animation, generating values with sine functions to create smooth, morphing scatter patterns rendered as SVG elements.

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

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.

D3 Selection Exploration

This example demonstrates D3’s data join and update pattern with animated circles. A sine wave controls the number and vertical position of circles, which are appended using the `selection.join` method. The animation runs on a 60-frame interval, updating circle `cx` and `cy` attributes. It uses d3.v7, with SVG rendering, to show enter, update, and exit handling as data changes over time.

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.

D3 Selection Exploration

This example demonstrates D3’s data join and selection patterns by animating a row of circles whose count and vertical positions oscillate with a sine wave. The code uses `d3.select`, `d3.range`, and `selectAll().data().join()` to update SVG circles at 60 frames per second, while a commented-out version shows the older `enter()`/`merge()`/`exit()` workflow. The visualization renders directly into the browser window via an SVG element sized to `window.innerWidth` and `window.innerHeight`, with no external data source.

D3 Selection Exploration

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.

D3 Selection Exploration

Animated circles demonstrate D3’s enter-update-exit cycle through the `join` method, using `selectAll` and `data` with data-derived sine waves to shift positions and radii. The visualization renders in SVG within the browser, updating at 60 frames per second via `setInterval`. Each frame recalculates a dynamic dataset from `d3.range`, illustrating how `join('circle')` automatically creates, updates, and removes nodes as data count fluctuates. The source uses D3 v7’s modular imports (`select`, `range`) and properties like `cx`, `cy`, and `r` to bind values directly to DOM attributes.
