D3 Selection Exploration (1st Stage)

D3 Selection Exploration

A set of circles animates smoothly across the screen, their count and vertical positions oscillating sinusoidally over time. The example demonstrates D3's data join pattern using `selectAll`, `data`, and `.join('circle')` to handle enter, update, and exit states. The SVG is sized to the full viewport, and an interval updates the dataset every 100 milliseconds, repositioning each circle via `attr('cx')` and `attr('cy')`. The source data is generated on the fly with `range` and `Math.sin`, rendering with D3 v6's SVG and animation capabilities.

D3 Selection Exploration

Fifteen circles undulate vertically in a sine-wave pattern, creating a rhythmic, animated wave across the browser window. The visualization demonstrates D3's data join and selection methods, where each frame generates new array data and updates the circles' positions. Using `d3.select`, `d3.range`, and the `.join()` pattern, the code binds fresh coordinates to SVG circle elements, which are animated every 60 milliseconds via `setInterval`. Rendering is done in SVG, with circles styled by radius and positioned absolutely by attributes like `cx` and `cy`.

d3 selection

A set of fifteen circles oscillates vertically in a sine wave pattern, driven by a continuous animation loop. The example demonstrates D3's selection and data-join methods, using `d3.select`, `d3.range`, `selection.data`, `enter`, `merge`, and `exit` to update SVG circle positions every frame. An interval running at 60 frames per second increments a time variable, which modulates each circle's y-coordinate based on its index. The code also includes commented-out alternative using `selection.join`, and renders directly to an SVG canvas sized to the browser window.

D3 Selection animation exercise

Fifteen circles oscillate in a sine wave pattern across the screen, with each circle’s radius enlarging as it descends and shrinks as it rises. The animation runs on a 60fps interval, updating positions based on time and index. Built with D3 v7, it uses `select`, `range`, and `join` to bind freshly generated data to SVG circle elements each frame.

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

A set of 15 circles animates in a sine-wave pattern across the browser window, with each circle's vertical position and radius oscillating over time. The code uses D3 v6's `select`, `range`, and `data` join methods to bind an array of computed objects to SVG circle elements. A `setInterval` at roughly 60 frames per second updates the data and re-renders via the `.join('circle')` pattern, which handles enter, update, and exit states seamlessly.

D3 Selection Exploration (2nd Stage)

This example uses the D3.js library to animate a dynamic set of circles across the screen. The visualization demonstrates a selection and join operation, where circles are appended or updated based on an incoming data array. The data itself is procedurally generated, with each circle's position and radius varying over time according to sine functions. The animation runs at 60 frames per second, using `select` and `join` APIs to manage the SVG elements.

A grid of ten circles undulates vertically in SVG, their radii and positions governed by sine waves. This animation explores D3's data joins by using `d3.selectAll`, `data`, and `.join('circle')` to bind an array generated with `range` to the circles. The setInterval-driven loop updates positions every 100ms, demonstrating how enter, update, and exit selections work, with the circle count oscillating between five and fifteen.
