This fork reproduces a Sol LeWitt wall drawing using dynamically generated SVG elements. It shows a grid of thin horizontal and vertical black lines intersecting within two overlapping circular masks, creating a geometric pattern where line density varies. The code uses the SVG DOM API to create `<rect>` elements, `<mask>` definitions, and `<circle>` shapes without any external libraries. The visualization generates 100 horizontal and 100 vertical stripes, each clipped by a complementary mask to produce the circular cutout effect against the full viewport.
