Forked from Fork of D3 Selection Exploration

This example is an exercise in using D3.js selection and join operations to create an animated visualization. It shows a dynamic set of 15 circles moving vertically in a sine wave pattern, with black vertical lines extending from each point and a polyline connecting them all. The animation updates at 60 frames per second using `setInterval`, and the positions are calculated with `Math.sin` in the `makeData` function. The code uses D3's `select`, `range`, and `line` functions, along with the `.join()` method to efficiently add or update SVG circles and path elements.

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 Exercise

This animated visualization demonstrates D3’s data-join and selection pattern by continuously updating a set of circles and connecting lines in an SVG scene. The code uses `selectAll` and `.join()` within `drawCircles` and `drawLines` to bind and update elements based on procedurally generated data from `makeCircleData` and `makeLineData`. Circle positions, radii, and colors oscillate with a time counter `t`, while lines link adjacent circles and inherit their stroke colors. Running at 60fps via `setInterval`, the example highlights how D3 v7’s `range`, `select`, and join methods handle dynamic, frame-by-frame updates in a React context.

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

This example demonstrates a D3 data join, where a set of 15 circles moves vertically in a sine wave pattern across the screen. The animation updates at 60 frames per second, recomputing each circle’s y-coordinate based on time and index. It uses the `select` and `range` functions from D3, along with the `.data()` and `.join()` methods to merge new data into the existing SVG circle elements.

D3 Selection Exploration

This example demonstrates D3’s data join and selection patterns by animating a row of circles whose count and vertical positions oscillate with a sine wave. The code uses `d3.select`, `d3.range`, and `selectAll().data().join()` to update SVG circles at 60 frames per second, while a commented-out version shows the older `enter()`/`merge()`/`exit()` workflow. The visualization renders directly into the browser window via an SVG element sized to `window.innerWidth` and `window.innerHeight`, with no external data source.

D3 Selection exploration

This example demonstrates how D3 selections manage dynamic data updates through animation. An SVG scene continuously redraws a set of circles and connecting lines, with the number of elements oscillating between 5 and 15 based on a sine wave. The code uses D3’s `select` and `range` functions, along with the `join` pattern to bind data to circle and line elements. Data is generated procedurally via `makeData`, updating positions and radii each frame. React serves as the framework wrapper, while the animation runs on a `setInterval` timer with a 60fps approximation.

D3 Selection Exploration

This example demonstrates how D3’s data join pattern animates a dynamic set of circles, whose count and vertical positions oscillate sinusoidally over time. Using `d3.select` and `d3.range`, it generates an array of points and binds them to SVG circle elements via `selection.data()` and `selection.join()`, updating `cx` and `cy` attributes each frame. The code runs a `setInterval` at 60fps, recalculating data with a time-based sine wave, while `d3` version 7.6.1 manages enter, update, and exit states automatically.

D3 Selection Exploration - Exercise

This example demonstrates D3's data-join and selection methods through an animated scatterplot of circles and vertical lines. The visualization continuously updates as `d3.range` generates new data points, with circles and lines re-rendered every frame. The code uses `selection.data().join()` for enter, update, and exit handling, alongside `selection.call()` for reusable visualization logic. Randomly colored circles refresh twice per second, while the underlying sine-wave pattern animates smoothly via `setInterval`. The SVG canvas spans the full window, with black-stroked circles connected to green lines.
