A fork of D3 Selection Exploration demonstrates how data joins drive animated SVG circle positions. Fifteen circles continuously update every 100 milliseconds, moving vertically along sine-wave paths across the full browser window. The code compares commented-out manual enter/update/exit patterns with the modern `selection.join()` API, which concisely handles circle creation, updating, and removal. Using d3's `select` and `range` functions, it renders circles with animated `cx` and `cy` attributes, showing the differences between explicit and implicit join methods in D3 v7.

Fork of D3 Selection Explorations

A fork of D3 Selection Explorations demonstrates the use of D3's data join and enter/update/exit pattern with animated SVG circles. It uses `d3.select`, `d3.range`, and the `selection.join('circle')` method to bind an array of generated data points to circle elements, updating their positions and radii every animation frame via `setInterval`. The visualization shows a sinusoidal wave of circles moving horizontally and vertically, with the number of circles varying over time as the data array length changes. The code relies on plain SVG rendering without additional libraries beyond D3 v6.

Fork of D3 Selection Exploration

This example explores D3 data joins with animated circles. A set of circles moves vertically based on a sine wave, with the number of circles oscillating over time. The code uses d3.select, d3.range, and the selection.join method to update the SVG. Data is generated in makeData.js and rendered as circles with attributes for radius, cx, and cy, refreshed every 60 frames per second.

Animated circles move in a sine-wave pattern across an SVG canvas, with their vertical position and radius oscillating over time. This fork dynamically updates the number of visible circles between 5 and 15 based on a continuously incrementing time variable. The code uses D3 v7's `select` and `range` functions, along with the data-join `.join()` method to efficiently add and remove circle elements each animation frame.

Fork of D3 Selection Exploration

An animated visualization renders a dynamic set of circles whose positions and radii oscillate using a sine wave, driven by a continuous timer. The scene updates every frame, re-binding new data to the existing DOM elements without a transition. The code uses D3 v6's `select` and `join` APIs to manage circle enter-update-exit cycles, with data generated by custom `makeData` and rendered as SVG. A small YouTube embed displays related source material alongside the live example.

Fork of D3 Selection Exploration

Animated circles move in a sinusoidal wave across an SVG canvas, with their vertical position and radius oscillating over time to create a flowing, generative pattern. The visualization demonstrates D3's data join and selection mechanisms by continuously updating the `x`, `y`, and `r` attributes of circle elements at 60 frames per second. Using D3 v6's `select`, `range`, and `join` APIs, the code generates fresh data points each frame from mathematical sine functions and applies them to the existing SVG selection, showing how D3 efficiently syncs data to DOM elements.

Fork of D3 Selection Exploration

A D3.js animation displays a set of circles that continuously move and change size, with their vertical positions and radii following a sine wave pattern over time. The visualization updates in real-time at 60 frames per second using a timer, generating 10 to 15 data points based on a sinusoidal function. The code creates and positions SVG circles using D3's selection API, specifically the `select`, `selectAll`, and `join` methods, while `range` and `scaleLinear` from the `d3` library generate numeric sequences. The circles are rendered as SVG elements, and the data is synthesized programmatically rather than sourced from an external dataset.

Fork of D3 Selection Exploration

This example demonstrates animated circle transitions driven by a continuous data stream. It shows how D3’s data join pattern updates SVG circle positions and radii in real time, with the number of circles and their attributes oscillating sinusoidally. The code uses `d3.select` and `selection.data` with `.join('circle')` to manage enter/update/exit, while `setInterval` triggers a refresh at 60 fps. Data is generated procedurally via `makeData`, which computes varying x, y, and r values based on a time parameter. The visualization highlights the simplicity of binding dynamic data to SVG elements using D3 v6.

Fork of D3 Selection Exploration

This example demonstrates dynamic data binding with D3 selections by rendering a set of circles that continuously change position, radius, and count over time. It uses the D3 v7 `select` and `range` functions along with the `join` method to manage enter, update, and exit states. The animation runs on a `setInterval` timer, updating a sine-wave-based dataset that controls each circle’s x-coordinate, y-coordinate, and radius. The visualization renders as an SVG canvas that fills the browser viewport, showing how D3’s data-join pattern efficiently handles fluctuating data sizes.
