This example demonstrates D3’s data join pattern by animating a set of circles whose positions, radii, and colors oscillate in a sinusoidal wave. The code imports `select` and uses a `setInterval` loop running at 60 frames per second, regenerating data via `makeData` and updating the SVG scene each tick. The `vizData` function applies a chain of `.selectAll('circle')`, `.data()`, and `.join()` to bind the new values, setting attributes for `cx`, `cy`, `r`, and `fill`. The explicitly commented-out path and transition code indicates the exploration focuses on the core join mechanics.

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.

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 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 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.

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.

This interactive example explores D3’s selection and data-join APIs. An SVG canvas fills the viewport, and a `d3.select` selection appends a root `<svg>` element. A function generates circles on a sine wave, updating their `cx`, `cy`, and `r` attributes through `selection.selectAll('circle').data(data).join('circle')`. The animation loop is commented out, so the visualization appears static; the code shows how to bind data to shapes and apply attribute updates via D3’s join operator.

Fork of D3 Selection Exploration

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 a set of animated circles whose vertical positions and radii oscillate smoothly over time, creating a wave-like pattern across the screen. The visualization uses the D3.js library (v6.6.2) to create an SVG canvas and a custom `join` operation for incremental updates. A timer-driven loop in JavaScript updates the data every 60 frames per second, while the `makeData` function generates new values using trigonometric functions (sine and cosine) based on a time variable. The code leverages D3's `select` and `range` utilities to manage the dynamic rendering, though the circles simply move continuously without any direct user interaction.
