This example demonstrates the enter-update-exit cycle in D3 data joins. An animated sine wave drives a set of circles across the screen, where the number of circles changes dynamically based on the oscillation, and each circle’s position and radius fluctuate over time. The visualization combines `d3.select`, `selection.data`, and `selection.join` from D3 v7 to bind data to SVG elements, with a `setInterval` loop updating the visualization at 60 frames per second. The data is generated procedurally using `d3.range` in the `makeData` function.

D3 Selection Exploration

Animated circles demonstrate D3’s enter-update-exit cycle through the `join` method, using `selectAll` and `data` with data-derived sine waves to shift positions and radii. The visualization renders in SVG within the browser, updating at 60 frames per second via `setInterval`. Each frame recalculates a dynamic dataset from `d3.range`, illustrating how `join('circle')` automatically creates, updates, and removes nodes as data count fluctuates. The source uses D3 v7’s modular imports (`select`, `range`) and properties like `cx`, `cy`, and `r` to bind values directly to DOM attributes.

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 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

This example demonstrates D3’s data join and update pattern with animated circles. A sine wave controls the number and vertical position of circles, which are appended using the `selection.join` method. The animation runs on a 60-frame interval, updating circle `cx` and `cy` attributes. It uses d3.v7, with SVG rendering, to show enter, update, and exit handling as data changes over time.

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 D3’s data-join pattern by animating a dynamic set of circles whose count, position, and radius oscillate over time. Using `d3.select` to append an SVG, the code generates synthetic data with `d3.range` and updates circles each frame via `selection.join('circle')`, binding new data and setting `cx`, `cy`, and `r` attributes. The animation runs on a `setInterval` at 60 FPS, showing seamless entry, update, and exit transitions with D3 v6’s `join` method.

D3 Selection Exploration

The visualization demonstrates how D3 selections can manage a dynamic set of circles whose positions, sizes, and count change over time. It uses `d3.select` and `d3.range` to generate data, with a `setInterval` updating the scene at 60 frames per second. The code employs the modern `.join('circle')` method to handle enter, update, and exit selections seamlessly, animating the circles' x and y coordinates based on sine waves. This example highlights the simplicity of data-driven updates in D3 v7.

Homework compact D3 Selection Exploration

This example demonstrates dynamic D3 selection and data-binding techniques by rendering an animated line of circles that oscillates across the screen. A sine-wave function generates a series of points whose positions, radii, and color shift continuously, with the line path updating each frame. The visualization uses `d3.select('body')` to append an SVG, `d3.range` to create data, and `selection.join` to bind circles and paths. A `setInterval` loop triggers updates at 60fps, while a `d3.line` generator computes the connecting path. The animation highlights how D3’s enter/update/exit cycle manages changing data counts.
