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 Slection

This example demonstrates a dynamic scatter plot of animated circles whose vertical positions oscillate sinusoidally over time. It uses React and the D3.js v7 library, specifically `select`, `range`, `data`, and the `join` API to create and update SVG circles each frame. The visualization runs on a 60Hz interval, recomputing data with the sine of a time variable to produce smooth, continuous motion across the screen.

D3 selection exploration

Ten animated circles form a sine wave pattern across the screen, with their vertical positions shifting continuously to create a smooth undulating motion. Using D3 v7's `select` and `range` functions, the code binds an array of ten data points to SVG circle elements via the `join` method, updating each circle's `cx` and `cy` attributes every frame at 60 frames per second. The example demonstrates both the data-join pattern and the newer `join` syntax as an alternative to the older `enter`/`merge` approach, with the animation driven by a `setInterval` timer that increments a time variable.

D3 Selection Exploration

This example demonstrates dynamic SVG circle generation and animation using D3 v7. An array of circles, generated from a sine-based function, continuously updates position and radius to create a flowing wave effect. The code uses D3's `select`, `selectAll`, `data`, and `join` methods to bind new data and manage enter/update/exit cycles. An interval-driven animation loop calls `vizData` at 60 frames per second, with data created by `makeData` using D3's `range` utility. The visualization runs in an HTML page with no external data sources.

D3 Selection Exploration

A dynamic set of circles animates across the screen, with positions and radii fluctuating sinusoidally over time. The visualization demonstrates D3's data join pattern, where an SVG selection binds to an array of generated points and updates each frame. Using `select` and `join`, the code continuously enters, updates, and exits circle elements based on data from `makeData`. The interval-driven animation synchronizes circle movement and sizing, showcasing D3 v6 selection methods within a React-compatible structure.

JavaScript Array

A animated SVG visualization of a JavaScript array, rendered as a row of circles whose positions and radii oscillate with a sine wave. It uses D3’s `select`, `selectAll`, and `join` to bind data generated by `makeData` to circle elements, updating them at 60 frames per second via `setInterval`. The React framework provides the project structure, while the axis-aligned waveform motion and pulsing sizes are driven by time-varying parameters `t` and the array index.

D3 Selections

A set of circles animates vertically in a sine wave pattern, changing count over time to demonstrate D3 data joins. The code uses `select` and `data` to bind an array of objects with `x`, `y`, and `r` properties to SVG circles, then applies the `join('circle')` pattern to handle entering and exiting elements. Animation runs via `setInterval` at 60 frames per second, with `makeData` generating positions based on `Math.sin` and a time parameter. The visualization highlights the decoupling of data generation from rendering through a reusable `vizData` function.

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.
