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.

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.

This example demonstrates animated sine waves rendered as a dynamic set of SVG circles whose positions and radii update continuously with time. The visualization uses `d3.selectAll`, `.data()`, and `.join()` to bind and update circle elements, while a `setInterval` loop calls `makeData()` to generate new coordinates and sizes. The code relies on D3 v6 APIs including `d3.line` and `d3.range`, with `vizData()` applying attribute updates for `cx`, `cy`, and `r`. The animation runs at 60 frames per second, creating a fluid, undulating pattern.

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 animated data-driven circles that flow in a sine wave pattern across the screen. The visualization updates at 60 frames per second, with each circle's position and radius changing over time based on a mathematical function. The implementation uses the D3.js library's `select`, `selectAll`, and `.data().join()` API to efficiently bind array data to SVG circle elements. The `vizData` function applies `attr` calls for the `r`, `cx`, and `cy` properties, while a separate `makeData` module generates the dynamic dataset with trigonometric calculations.

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 demonstrates D3’s data join pattern through an animated sequence of circles whose positions and radii oscillate over time. The visualization updates at 60 frames per second by recreating a dataset with `makeData` and passing it to the `vizData` function, which uses `selection.selectAll('circle')` and `.join('circle')` to bind new data points. Each circle’s `cx`, `cy`, and `r` attributes are set from the data properties, producing a smooth wave-like motion across the SVG canvas. The visualization relies on D3 v6’s `select`, `range`, and `scaleLinear` utilities, with the `svg.call()` method triggering the drawing routine.

Fork of D3 Selection Exploration

This example demonstrates dynamic animated circles moving in a sine-wave pattern across the screen, with vertical lines extending from each circle's edge. It updates at 60 frames per second via a `setInterval` callback. The visualization uses D3 v6's `select`, `selectAll`, `range`, and `scaleLinear` (though the latter is only in commented code) to bind data and render SVG elements. The `join` method handles entering, updating, and exiting circles and lines, while `makeData` generates positional values based on time and index.

D3 selection exploration demonstrates animated circles and paths within an SVG canvas. Each of 20 circles moves vertically and changes radius based on a sine wave, while its color randomly updates every frame using a hexadecimal generator. A blue path element is appended with static coordinates but never updated. The visualization runs at 60 frames per second via `setInterval`, calling the custom `vizData` function with newly generated data from `makeData`. It utilizes D3 v6’s `select` and `selection.enter()` API for data joins.
