This example generates a generative art composition in the style of Sol LeWitt, using an SVG canvas and D3.js. Horizontal and vertical striped bars are combined with two masks containing scaled D3 symbols, creating an intersecting interplay between the bar grid and the shapes. The code uses `d3.select`, `d3.range`, `d3.symbols`, and `d3.symbol` with `d3.symbol()` to render the masked paths. The output is a purely procedural, abstract visualization driven by layout and masking logic, with no external data source.
