This live D3 example demonstrates the selection and merging of data-driven SVG circles, with positions adjusting over time based on sine waves. At each animation frame, the code uses D3's `select`, `range`, and the `join` selection API to reconcile the current dataset with rendered circles, updating their `cx` and `cy` attributes. The visualization shows smooth enter, update, and exit behavior as the number of circles varies with the sine function at 60 frames per second.

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.

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 D3 selection exploration shows a variable number of circles moving in a sine-wave pattern across an SVG canvas. The visualization demonstrates D3's selection API, specifically the `join` operation for efficiently managing entering, updating, and exiting nodes as the data array changes over time. Using `setInterval` to update a time parameter every 200 milliseconds, the code generates new data points via `range` and applies `attr` updates for position and radius. The example forks a v3-era D3 exploration and renders with standard SVG animation.

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

A live SVG animation demonstrates dynamic data selection and rendering with D3. A set of circles moves smoothly across the canvas, with positions and radii continuously updated by a sine wave function. The visualization uses D3’s selection API (`select`, `selectAll`, `join`) to efficiently bind and update circle attributes in real time. Data is generated procedurally via `makeData`, while `vizData` handles the incremental visual updates, creating a fluid, responsive display.

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

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

This example explores D3 data joins and SVG animation as a sine wave drives a changing dataset. A set of circles and connecting lines is redrawn on each frame, with the line stroke-width bound to each circle’s radius. The code uses `d3.select`, `selection.data`, and `.join()` to update shapes, while `d3.range` and `scaleLinear` in `makeData` generate positions and sizes.
