This example shows a row of twenty circles evenly spaced across the screen, all centered vertically. The visualization uses D3.js version 6.7.0 to bind an array of data points to SVG circle elements, setting each circle’s x-coordinate, y-coordinate, and radius based on the data. The code pulls data from a simple generated array via `d3.range`, and positions the circles using the `select`, `selectAll`, and `join` methods. The page is styled with a hidden overflow and a custom Google font, though the dataset referenced in the README is not actually loaded in the running code.
