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.

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.

compact D3 Selection Exploration

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 following along

Animated D3 line and circle rendering demonstrates dynamic data binding, where sine-wave points continuously update through a `d3.line` path generator. The visualization uses `selectAll` with join operations to update SVG elements each frame, driven by a `setInterval` loop. Data generation via `makeData` recalculates positions, radii, and colors from the time variable, while the D3 v7 library provides the core selection and shape-generation APIs. The resulting organic motion shows how D3's data-join pattern efficiently manages changing datasets.

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 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 dynamic D3 selection and data binding by animating a set of circles that move and resize in a sine-wave pattern. Using `d3.select`, `selection.data`, and `.join`, it updates the SVG circle positions and radii every frame at 60fps via `setInterval`. The `makeData` function generates the x, y, and r values, while the `vizData` module applies the attributes. Rendering relies on SVG elements with no transitions, showing raw join behavior. The data is synthetic, derived from trigonometric functions, and the visualization fills the browser window.

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.

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.
