This example visualizes the recursive integer sequence A133058, where each term depends on the greatest common divisor (GCD) of its index and the previous term, producing a pattern of scattered points across 850 iterations. A dark circle marks each (n, a) pair, with all points initially converging at the chart’s center before animating outward to their final positions via staggered transitions. The visualization uses D3 v5 with linear scales and SVG circles, computing the GCD with a custom Euclidean algorithm function to generate the data. Axis generation relies on `d3.axisBottom` and `d3.axisLeft`, while the animation applies chained `.transition()` and `.delay()` methods.
