This example demonstrates a mask-based visual effect that combines two sets of overlapping SVG rectangles, creating a crosshatch pattern of thin horizontal and vertical lines. The full viewport is covered by 100 horizontal and 100 vertical strips, each partially revealed through circular mask regions defined using D3’s `symbol` API. Two masks are layered: the first shows a white circle against a black background, while the second inverts the circle’s role, allowing the rectangles to appear only outside the central circular area. The rendering uses D3 version 6.6.1 with SVG output.

MaskTest

This example demonstrates how SVG masks can create intersecting geometric patterns. Two sets of thin, full-length rectangles—horizontal and vertical—are drawn across the entire viewport using d3.range and d3.selectAll. Each set applies a different circular mask: one reveals a white circle against a black background, while the other inverts the mask, hiding the circle. The result is a crosshatched grid with a central circular region where the two masked layers visibly interact. The code uses D3 v6 selections and the SVG `<mask>` element.

Full MaskTest 2

Two sets of horizontal and vertical striped rectangles fill the screen, each masked by a different pattern of D3 symbols. The first mask uses white symbols on a black background, while the second inverts this, creating a crosshatched visual effect where the symbol shapes appear cut out of the stripes. Built with D3 v6, the code uses `range`, `symbols`, and `symbol` to generate the mask patterns, and `selectAll` with `join` to render the rectangles. The SVG output is sized to the full browser window.

Fork of MaskTest 1

This example creates a geometric grid pattern using D3 v6, rendering horizontal and vertical stripes across the full browser viewport. Two SVG masks reveal the stripes through circular windows in the center of the screen. The first mask shows vertical lines inside a white circle on a black background, while the second mask inverts this effect. The code uses D3’s `select`, `range`, and `join` methods to generate the rectangles, with SVG `mask` elements and `circle` shapes determining the visible regions.

svg mask

This example demonstrates the visual effect of SVG masks by layering horizontal and vertical stripes over a full-viewport canvas. It creates two circular masks, one with a white circle on a black background and the other with a black circle on a white background, then applies them to alternating sets of 50 thin rectangles. The code builds the entire scene programmatically using the Document Object Model (DOM) methods such as `createElementNS` and `setAttribute`, without any external libraries, and renders everything directly in SVG.

multi masks

This example creates an abstract pattern of 100 horizontal and 100 vertical stripes overlaid on an SVG canvas, with each stripe masked by one of two complementary masks. The masks are defined using D3’s `mask` element, where black and white rectangles and symbol shapes (from `d3.symbol`) determine visibility. The code uses D3 selections and `join` to bind data from `d3.range`, and applies masks via `attr('mask', 'url(#mask-1)')`. The result is a woven, crosshatched visual effect generated entirely in the browser.

mask experiments

This example demonstrates the interplay of two complementary SVG masks. It first shows a set of horizontal stripes visible only within a circular window, then displays vertical stripes that are hidden inside the circle while remaining visible outside it. The piece creates a stark geometric contrast between the two masked regions. The visualization is generated entirely with the SVG `mask` element and basic `rect` and `circle` primitives, using white and black fills to define luminosity. The code dynamically constructs one hundred stripes for each orientation, with the masks applied via URL references to `#circle-mask` and `#circle-mask-2`.

SVG Foundamentals

This example demonstrates how SVG masks and primitive shapes combine to create a striking visual effect. It displays 100 horizontal rectangles filling the viewport, with a circular mask revealing only the area inside a 200-pixel-radius circle centered on the screen. Using D3.js version 7.6.1, the code binds data via `d3.range` and `selectAll` to generate the rectangles, then appends a `mask` element containing a black background rectangle and a white circle to control visibility. The rendering approach relies entirely on SVG elements and DOM manipulation through `d3.select`.

D3.js fundamental

This example demonstrates how SVG masks can be used to create geometric cutouts in layered grid patterns. It renders 100 horizontal and vertical rectangles across the full viewport, each masked by a circle that reveals or hides portions of the grid. The code uses D3.js v7 with the `select`, `selectAll`, and `range` APIs to generate the shapes, while two separate `<mask>` elements with contrasting fill colors control visibility. A white-filled mask with a black circle creates the first cutout, and an inverted mask creates the second, producing two distinct circular viewing windows.
