d3 selections

Fifteen circles animate across the screen in a wave-like pattern, expanding and contracting as they move. The visualization uses d3 selections to bind an array of data to SVG circle elements, updating their cx, cy, and r attributes every frame. The animation is driven by a setInterval loop that recalculates each circle’s position and radius using trigonometric functions, with d3.select, range, and interval from the d3 library.

Fork of D3 Selection Exploration

A live animation renders a set of circles whose vertical positions oscillate sinusoidally over time. Built with D3 v6, the visualization uses the `select` API to append an SVG canvas and updates the scene at 60 frames per second via `setInterval`. It applies the modern `join` operation to bind the dynamic data to circle elements, animating their `cx` and `cy` attributes as the wave pattern shifts. Data is generated procedurally with `range` and `scaleLinear` from the D3 library.

Fork of D3 Selection Exploration

An animated visualization renders a dynamic set of circles whose positions and radii oscillate using a sine wave, driven by a continuous timer. The scene updates every frame, re-binding new data to the existing DOM elements without a transition. The code uses D3 v6's `select` and `join` APIs to manage circle enter-update-exit cycles, with data generated by custom `makeData` and rendered as SVG. A small YouTube embed displays related source material alongside the live example.
