Animated circles sweep in sine patterns across the screen, with their radii and vertical positions oscillating over time. The visualization demonstrates D3's enter/update/exit lifecycle: a `selectAll('circle')` query is joined with a data array via `.join('circle')`, which handles node creation, attribute updates, and removal as the dataset changes each frame. The code uses `d3.select` and `d3.range` to build an SVG scene, updating positions and sizes at 60 frames per second via `setInterval`. The data is procedurally generated with trigonometric functions, and the rendering is pure SVG 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.

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 (Enter - Update Selections Clearly Separated)

This example demonstrates the D3 enter-update pattern by animating a set of fifteen circles along a sine wave. Every five seconds, the data array is regenerated, and the code clearly separates the enter selection—which appends new circles with `circles.enter().append('circle')`—from the update selection that repositions existing elements via `circles.attr('cx', ...)` and `circles.attr('cy', ...)`. Using D3 v7 with SVG, the visualization shows how identical data keys map to existing nodes, avoiding duplication. The animation loops indefinitely using `setInterval`, and the rendering adjusts to the full browser window size.

D3 Selection exploration

This example demonstrates D3 selection and data-join patterns by animating a series of circles and connecting lines across a full-screen SVG. As time progresses, the circles oscillate vertically along sine waves while lines link consecutive points. The code uses `d3.select`, `d3.range`, and the `selection.join` method to bind and update elements each frame. Rendering is driven by a `setInterval` loop that regenerates the data and re-applies the `makeCircle` and `makeLine` functions, highlighting how D3 manages enter, update, and exit states.

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

This example explores D3 selections and data joins through an animated visualization. A sinusoidal wave of circles moves across the screen, with the number of circles oscillating based on a time variable. The code uses d3.select and d3.range to generate data, then applies the selection’s `.data()`, `.join()`, and attribute setters to update SVG circle positions each frame. The animation runs via `setInterval` at 60fps, with sine functions driving both the vertical placement and count of circles, demonstrating enter, update, and exit behavior.

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.
