This example reproduces a Sol LeWitt-inspired drawing using overlapping geometric masks. The visualization displays a grid of black bars (vertical and horizontal) that intersect with two rows of outlined circles, created by applying two distinct SVG masks—one inverted and one not—to the bar patterns. The code uses D3.js (v6) to dynamically generate the scene, calculating bar placement based on the browser window’s dimensions. It leverages D3’s `selectAll`, `range`, and `join` methods to efficiently append and configure SVG elements, while `d3.symbol` generates the circle paths. The rendering is fully SVG-based within a React-free environment.
