d3 selection

D3 selection exploration

This example demonstrates animated selection and data-join techniques in D3, showing fifteen circles bobbing vertically in a sine-wave pattern across the screen. The visualization uses d3.select and d3.range to generate data, then applies the .join('circle') method to bind that data to SVG elements. A setInterval loop running at 60 frames per second updates the circles’ cx and cy attributes, with the y-position calculated from a sine function of the data index and a time variable t. The animation relies entirely on d3 v7’s selection methods and SVG rendering.

D3 Selection Exploration

This example demonstrates D3 data joins with animated circles that continuously update position and radius. It uses D3 v6’s `select`, `range`, `scaleLinear`, and the `.join('circle')` pattern to bind new data each frame. The `setInterval` drives a 60fps animation, generating values with sine functions to create smooth, morphing scatter patterns rendered as SVG elements.

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 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 and Exploration

A collection of animated circles moves across the screen, their positions and sizes oscillating in a wave-like pattern over time. The visualization demonstrates dynamic data binding and updates in D3 v7, using `select`, `range`, and the `.join()` method to create and modify SVG circle elements at 60 frames per second. The animation is driven by `setInterval`, recalculating each circle's x-coordinate, y-coordinate, and radius based on sine functions that incorporate a continuously incrementing time variable.

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.

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.

D3 Selection Exploration

Fifteen circles undulate in an animated sine-wave pattern, with positions and radii oscillating smoothly over time. The example demonstrates D3's selection and data-join mechanics by using `selectAll` and `join` to bind an array of generated data to SVG circle elements. Rendered in SVG, the animation updates every 100 milliseconds via `setInterval`, incrementing a phase variable to drive the motion. The code imports `select` and `range` from D3 v7, showing the modern `join` pattern as a concise replacement for the older `enter`/`merge` approach.
