This example demonstrates how SVG masks can create two distinct circular cutout effects on a grid of overlapping rectangles. One mask, defined with a black background and white circle, reveals only the vertical stripes; the other, with a white background and black circle, controls visibility of horizontal stripes. The code builds the full-screen SVG and all elements programmatically using `document.createElementNS` and `setAttribute` in vanilla JavaScript, without any external libraries. The result is a visual interplay of lines that form a transparent circular window at the center of the viewport.

Fork of SVG Fundamentals

This example demonstrates SVG masking by layering a grid of horizontal and vertical rectangles over a circular cutout. The rectangles are created dynamically using the DOM API `document.createElementNS` with the SVG namespace. Two complementary masks, `circle-mask` and `circle-mask-2`, alternate between white and black fills to control visibility, producing a striped pattern inside the circle while keeping the surrounding area solid. The code relies on raw SVG manipulation rather than a visualization library, with only the `d3-selection` API imported but not actively used.

Fork of Fork of SVG Fundamentals Horizontal Vertical

This example demonstrates how SVG mask elements create intersecting visual patterns from horizontal and vertical stripes. The code uses raw SVG APIs—`document.createElementNS`—to build a full-window canvas with 100 horizontal rectangles masked by a white circle and 100 vertical rectangles masked by a complementary mask. Each mask combines a solid fill with a central circle, revealing or hiding stripes to form a cross-shaped overlap at the center. The result layers two sets of lines that visually blend through the transparent mask regions.

Fork of SVG Fundamentals Horizontal

This example demonstrates SVG masking by confining a pattern of horizontal and vertical lines to a circular region at the center of the screen. The code generates 100 horizontal strips and 100 vertical strips using the `document.createElementNS` API, while a mask containing a white circle over a black rectangle restricts visibility of the horizontal lines. The result is a grid where only the intersection inside the circle remains visible, created entirely with vanilla JavaScript and no external libraries.

SVG Fundamentals

This example demonstrates the visual impact of SVG masks, using them to selectively reveal or hide overlapping shapes. It creates a full-screen canvas filled with horizontal and vertical stripes by generating one hundred thin rectangles for each direction. A circular mask isolates a central area where the stripes remain visible, while a second, inverted mask produces a contrasting ring effect by revealing the vertical stripes outside the circle. The code builds the SVG document dynamically through the Document Object Model, creating elements like rectangles and masks using `createElementNS` and `setAttribute` within JavaScript.

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 demonstrates how SVG masks can create complex visual effects by combining shapes. A white rectangle covering half the canvas contains a black circle and a smaller white circle, which together punch holes in the mask. The page renders 100 horizontal strips, each with a mask applied, creating an alternating pattern of visible and hidden regions. The code uses raw JavaScript to manipulate SVG elements directly, setting attributes like width, height, and fill on rectangles and circles within a masked group.

Fork of SAP_SVG_JS_FUNDAMENTALS

This example demonstrates a geometric pattern created entirely with SVG masks, rendering a circular window surrounded by a grid of horizontal and vertical stripes. The visualization uses two custom mask definitions—one with a white circle on a black background and another with a black circle on white—to selectively reveal and hide alternating sets of rectangles drawn across the full viewport. Built with vanilla JavaScript and the SVG DOM API, it dynamically sizes the canvas to the browser window and constructs 100 lines in each direction using `createElementNS` and `setAttribute`, producing a layered, intersecting lattice effect without external libraries.

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.
