This example generates a grid of horizontal and vertical stripes that intersect to create a geometric pattern. It uses SVG masks with circles to reveal or hide different sections of the stripes, producing a composition reminiscent of Sol LeWitt’s wall drawings. The code leverages D3 v7 selection methods, including `select`, `append`, and `join`, along with `range` to create 100 rectangles for each direction. The visualization is fully responsive, sized to the browser window, and includes hover effects that change the fill color to magenta.
