Fork of D3 Selections (with dots and lines)
This example demonstrates a dynamic visualization of circles connected by lines, animating as the data changes over time. Using D3.js version 6.7.0, the code employs `select`, `scaleLinear`, and `range` functions to generate data points with varying x, y, and radius values, while the `join` and `selectAll` methods update the SVG elements. The animation runs at approximately 60 frames per second, with the `setInterval` function updating the dataset and redrawing the circles and connecting lines with alternating stroke widths, all rendered as SVG in the browser window.
