This example displays a pattern of black vertical and horizontal stripes through a circular aperture. The SVG uses dynamically created `<rect>` elements to construct the stripe grids. A white circular overlay, styled with CSS, masks a second SVG containing perpendicular lines, creating an optical moiré effect as the two grids intersect. The page is built with plain HTML, CSS, and JavaScript, using the SVG namespace and DOM manipulation via `createElementNS`.

This example creates an SVG mask that reveals horizontal stripes through a circular window. The code generates 100 horizontal rectangles, each masked by a circle centered on the screen, while 100 vertical rectangles overlay the full canvas without masking. All shapes are built dynamically using the SVG namespace with `document.createElementNS`, and the mask is defined with a black background rect and white circle to control visibility. The result is a simple geometric pattern combining masked and unmasked grid-like elements.

This example showcases a geometric pattern created by layering two sets of parallel stripes overlaid with circular masks. It uses the D3.js library to build SVG elements and generate the mask paths, drawing on the `range`, `select`, `append`, `attr`, and `symbol` APIs from D3. The code creates a 100×100 grid pattern where overlapping translucent stripes form a subtle checkerboard effect within a central circle, demonstrating the use of reusable SVG masks and declarative data-driven rendering.

This example creates an SVG visualization that displays a series of horizontal stripes, with a circular mask revealing the central portion of the pattern. The visualization uses the HTML5 Canvas API indirectly through SVG elements, specifically manipulating SVG `rect` elements and a `mask` definition. The code generates 100 rectangles, each 10 pixels tall and spaced 20 pixels apart, all constrained by a `circle-mask` that creates a circular viewport. The mask itself contains a white background `rect` and a black `circle` positioned at the center of the viewport, effectively cropping the striped pattern into a circular shape.

A geometric pattern of horizontal and vertical lines intersects within a circular window, creating a crosshatched grid centered on the screen. The visualization uses two SVG masks to reveal alternating line orientations: one mask shows horizontal stripes through a white circle, while the other displays vertical stripes around it. Built with React and D3, the code generates 100 rect elements in each direction, then applies mask circles of 200-pixel radius to control visibility.

This example creates an interactive SVG visualization by generating a series of horizontal stripes across the full canvas, with a circular mask applied to reveal only the central region. The code uses the raw SVG DOM API (`document.createElementNS`) to construct a mask element containing a white circle over a black rectangle, then appends 100 overlapping rectangular bands that reference this mask via `url(#circle-mask)`. The visualization employs React as the framework but relies on vanilla JavaScript for rendering, with the page adaptively sized to `innerWidth` and `innerHeight`. The result is a simple pattern of layered color bands emerging through a circular window.

This example uses raw JavaScript and the SVG API to dynamically construct a full-window visualization. It creates two distinct masks on an SVG canvas: a white circle on a transparent background and a white rectangle with a black circular hole at the center. The code then generates 100 horizontal and 100 vertical thin rectangles, applying these masks to reveal a grid-like pattern of intersecting lines against a plain background. The result is a geometric composition built entirely through procedural DOM manipulation without any external libraries.

This visualization displays a grid of thin horizontal and vertical rectangles, with a circular region in the center revealed by two mask layers. The first set of horizontal strips and vertical strips are generated using `d3.select`, `d3.range`, and the `.join` method to create SVG `rect` elements. Two SVG masks—one with a white circle on black, the other with a black circle on white—are applied to create the central circular aperture, resulting in an intersecting crosshatch pattern.

This example uses SVG masks to create an intersecting grid of horizontal and vertical lines, revealing a circular window at the center. The code employs `d3.select` and `d3.range` to generate two sets of 100 rectangles, one for each orientation, and applies a mask with a white circle over a black background to the horizontal lines, and a mask with a black circle over a white background to the vertical lines. The result is a cross-hatched pattern that becomes visible only inside the central circle.
