An animated array of green circles and vertical lines undulates across the screen, with circle radii and y-positions oscillating sinusoidally. The visualization demonstrates D3's data-join pattern by using `selection.join` to update both `circle` and `line` elements, while an ES6 named import separates the rendering logic in `vizData.js` from the procedural data generation in `makeData.js`. A `d3.scaleLinear` maps circle radii to stroke colors ranging from white to green. The animation runs via `setInterval` at roughly 60 frames per second, updating the scene with new, parameterized data points.

Fork of D3 Selections Explorations - exercise - lines

A set of colored circles and connecting lines animates in a wave pattern across the screen. The visualization uses D3 selections with `join` to update SVG circles and lines every frame, driven by a `setInterval` loop. Data is generated procedurally using `d3.range` and sine functions for position, radius, and color. The code explicitly imports `select` and `range` from D3 v7, updating attributes like `cx`, `cy`, `r`, and line endpoints in real time.

Fork of D3 Selections (with dots and lines)

This example demonstrates a dynamic visualization of circles connected by lines, animating as the data changes over time. Using D3.js version 6.7.0, the code employs `select`, `scaleLinear`, and `range` functions to generate data points with varying x, y, and radius values, while the `join` and `selectAll` methods update the SVG elements. The animation runs at approximately 60 frames per second, with the `setInterval` function updating the dataset and redrawing the circles and connecting lines with alternating stroke widths, all rendered as SVG in the browser window.

A dynamic swarm of circles undulates across the screen, with each circle’s position and radius shifting over time based on sine-wave functions. The visualization demonstrates D3’s data-join pattern, using `selection.selectAll`, `.data()`, and `.join('circle')` in the `vizData.js` module to bind and update SVG elements. Data is generated procedurally by `makeData.js`, which uses `d3.range` and `d3.scaleLinear`. An animation loop runs at 60 frames per second via `setInterval`, calling the visualization with freshly computed values, producing a smooth, organic motion without explicit transitions.

Fork of D3 Selection Exploration

A fork of an interactive D3 selection exploration demonstrates animated circles moving vertically along a sine wave, with their radii and positions updating dynamically. Generated data from `makeData.js` drives the visualization, which uses D3's `selectAll`, `data`, and `join` methods to bind circles and a path to the SVG. The `line()` generator renders a connecting curve, while a `setInterval` loop updates the scene every frame. The visualization relies on D3 v6.6.2, rendering SVG elements in the browser, with circles colored in pastel pink.

An animated SVG visualization of swirling geometric patterns, demonstrating dynamic data binding with D3 selections. Hundreds of teal lines and rainbow-colored circles continuously update their positions and radii in a dark viewport, creating a rhythmic, organic motion. The code uses D3 version 7’s `select` and `selectAll` APIs with a `join` method to handle enter, update, and exit states for both line and circle elements. Data is generated procedurally via custom `makeData` and `vizData` functions, using trigonometric calculations and `interpolateRainbow` for color mapping, with updates triggered by a JavaScript `setInterval` loop.

Fork of D3 Selection Exploration

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.

A looping animation renders a row of colored circles that undulate and change radius over time while a black line traces their connected path. The example demonstrates D3’s data-join and selection methods, using `selectAll` and `join` to update SVG circles and a `d3.line` generator for the path. Circle positions and sizes are computed from sine functions, with colors shifting through a custom shading function. The animation runs at 60 frames per second via `setInterval`, and the SVG canvas fills the browser window.

This visualization demonstrates a dynamic scatterplot of colored circles that move and resize over time. Animated via a 60-frames-per-second interval, the circles' positions, radii, and hues are recalculated continuously. The implementation uses D3.js selection and join APIs, specifically `d3.select`, `d3.range`, and `.join('circle')`, to manage SVG circle elements. The `vizData` function updates circle attributes through `selection.selectAll('circle').data(data).join('circle')`, while `makeData.js` generates data with sinusoidal motion and color interpolation using `d3.interpolateRgb`. The SVG output is rendered directly to the browser window.
