Forked from MaskTest

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.

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.

Full MaskTest 1

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.

Fork of SVG Fundamental

This example demonstrates how SVG masks can selectively reveal or hide parts of overlapping shapes. It creates two circular masks—one filled red for horizontal stripes and another inverted with a white background and black circle for vertical stripes. Using the D3.js `selection` module for logging, the code builds 40 horizontal and vertical rectangles via the DOM API, applying each mask URL to alternate stripe orientations. The result is a crosshatch pattern formed by masked rectangles over a full-screen SVG, showcasing mask composition and reuse.

This example demonstrates a striped mask effect by layering two sets of rectangles with intersecting patterns. The SVG output shows vertical black bars overlaid with horizontal black bars, where both layers use SVG masks to reveal or hide portions of the rectangles. The code uses D3 v7’s `select`, `range`, and `data` joins to generate 100 rectangles per axis across the full viewport. The first mask exposes a rectangular region while the second mask inverts it, creating a dynamic checkerboard-like visual from the overlapping shapes.

This example shows a grid of horizontal and vertical stripes across the full viewport, with a circular region at the center appearing brighter against the surrounding dark mask. The code uses D3 v7 selections to append two groups of rectangles, each generated from a `range(100)` data array, and assigns SVG masks to each group. The first mask contains a black rect with a white circle, while the second uses inverse colors, creating the overlapping visual effect.

Fork of Fork of Fork of SVG Fundamentals - D3

This example demonstrates a full-screen grid of horizontal and vertical bars revealed through two circular masks. The visualization uses D3’s `select`, `range`, and data joins to generate 100 rectangles in each orientation, with CSS masks defining a central circular viewport. Two SVG masks—one with a black background and white circle, another inverted—control which bar segments remain visible, creating a crosshatch pattern that fades at the edges. The rendering relies on the SVG `<mask>` element and D3’s `join` API.

Fork of HTML Starter

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.
