This example reproduces a Sol LeWitt-inspired geometric composition entirely through SVG elements. It shows a grid of horizontal and vertical bands that intersect within a centered circular boundary, creating a patterned interplay of lines and negative space. The code constructs the visualization using raw JavaScript and the SVG DOM API, creating two masks—one with a black background and white circle, the other with the inverse—to alternately reveal horizontal stripes inside the circle and vertical stripes outside it. One hundred rectangles are generated for each orientation, each masked to produce the final layered effect.
