This example demonstrates how D3 selections and the data join pattern work by animating a set of circles and a connected line. The code uses `d3.select`, `d3.range`, and the `selection.join` method to bind an array of points to SVG circles, while a `d3.line` path is redrawn each frame. The data is generated procedurally from a sine wave, and the animation updates every 100 milliseconds using `setInterval`. The visualization shows a shifting waveform with a fixed set of circular markers, emphasizing how D3’s enter, update, and exit logic operates in a live rendering loop.

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 Exploration

This example demonstrates the update and join pattern of D3 selections, animating a set of 15 circles and a connecting line path over time. The circles and path are re-rendered every frame using a `setInterval` loop, with their vertical positions and radii driven by a sine function of an incrementing time variable. The code uses `d3.select`, `selection.selectAll`, `selection.join`, and `d3.line` to bind new data arrays generated by `makeData` to SVG elements, showing how D3’s data-join syntax handles dynamic updates efficiently. The visualization runs in a full-window SVG canvas.

D3 Selections (with dots and lines)

This example demonstrates how D3 selections manage live-updating data through the `join` pattern as an alternative to `merge`. Animated dots and connecting lines respond to a continuously changing dataset generated by sine functions, with circle positions and radii shifting over time. The visualization uses D3 v6’s `selectAll`, `data`, and `join` to bind dynamic data to SVG elements, while `setInterval` drives the animation at roughly 16 frames per second. The code separates data generation and visualization logic into distinct modules, showcasing reusable D3 selection patterns.

D3 Selection exercise

This example demonstrates D3 selection and data-join concepts through an animated line chart with pulsating circles. The visualization renders two stacked SVG layers, with the lower layer drawing a sine wave using `d3.line` and the upper layer displaying circles whose radii scale with their y-position and x-coordinate. Colors cycle through a rainbow palette based on each circle's vertical position. Using `d3.select`, `d3.range`, and sequential joins, the code updates the visualization at 60 frames per second via `setInterval`, with transitions on circle fill attributes creating smooth color changes.

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 Explorations

A collection of animated circles demonstrates D3's data-join pattern for dynamic SVG rendering. The visualization continually updates data via a JavaScript interval, adjusting the number and positions of circles based on sine waves. Using D3 v6, the code employs `select`, `range`, and the `join` method to bind new data to existing SVG circle elements, updating their `cx` and `cy` attributes at 60 frames per second. The example highlights the simplicity of enter, update, and exit handling within a single chained call.

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 animation demonstrates D3’s data-join pattern by continuously updating a series of colored circles and connecting lines. Each frame, `setInterval` regenerates data with changing positions, radii, and counts, while `selection.data().join()` efficiently creates or updates circles and lines. The SVG uses `selectAll` and `enter/update/exit` behavior, with colors assigned cyclically via a helper function. The example highlights D3’s declarative binding of data to visual elements, using the `vizData` function to apply dynamic geometry and stroke styles.
