Fork of Circles with D3
This visualization creates a striking striped pattern using 100 horizontal rectangles of varying heights, each rendered in SVG. The code uses a D3 mask with a circular cutout to reveal the colored bars through a black overlay, producing a lens-like effect. Built with D3 v7, it employs `select`, `range`, and `join` to bind data to rect elements, while the mask is constructed with custom SVG elements.
