Three visualizations compare different approaches to handling overlapping circles in SVG: default rendering, semi-transparency with `fill-opacity`, and SVG masks. The masked version uses a `defs` element containing `mask` definitions that hide the inner portion of each larger circle by overlaying a black circle, revealing only the visible outer ring. Built with D3 v4, the example uses `d3.select`, `selectAll`, and `.enter().append()` to create the circle elements, while the mask logic relies on SVG's native `mask` attribute and `url()` references within the inline JavaScript.

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.

d3

A grid of alternating horizontal and vertical SVG rectangles is masked to reveal a circular window at the center of the viewport. The example demonstrates how to construct and apply multiple SVG masks using D3’s selection and data-join methods, specifically `selectAll` with `range` and `join('rect')`. Two masks (`circle-mask` and `circle-mask-2`) use black-and-white rectangles and circles to control visibility of the 50 strips in each direction.

D3

This example demonstrates layered masking in SVG to create a grid of horizontal and vertical lines that intersect around a central circular opening. It uses D3’s `select` API alongside raw DOM manipulation to append two complementary masks, each defining a circular region of white or black fill. The code renders 100 horizontal and 100 vertical rectangles, applying one mask to each set so that lines are hidden or revealed in alternating patterns around the circle. The result is a moiré-like visual effect built purely from basic SVG shapes and mask definitions.

D3 mask all shapes

This example demonstrates how D3.js mask elements can selectively hide or reveal overlapping shapes, creating a geometric grid pattern of 100 horizontal and vertical rectangles. The visualization uses two SVG masks with inverted color schemes—one black with white symbols and one white with black symbols—to control visibility across the layers. It employs `d3.select`, `d3.range`, `d3.symbol`, and `d3.symbols` to generate and position the mask paths, while SVG rects and mask attributes handle the rendering. The code adapts automatically to the browser viewport dimensions.

New D3 Shapes SVG Fundamentals

This example demonstrates how D3 SVG masks combine with geometric primitives to create layered visual effects. Horizontal and vertical rectangles are drawn across the full viewport, then clipped through two masks—one using standard black-on-white fill logic and another inverted. Each mask contains a group of D3 v3 symbol paths rendered from the `symbols` API, with their positions and sizes defined by `range` and transform translations. The result shows how `selectAll`, `join`, and mask attributes control visibility across overlapping elements.

Learn D3

This example demonstrates how SVG masks can create a striking visual composition using only rectangles and circles. It renders 100 horizontal and 100 vertical thin rect elements across the full viewport, with each set masked by a circular aperture defined via native SVG `mask` elements. The first mask uses a white circle on a black background, while the second inverts the colors to alternate visibility between the two rectangle sets. No D3 library calls appear in the code; instead, it relies on `document.createElementNS` and `setAttribute` for all SVG construction, making it a pure vanilla JavaScript and SVG demonstration.

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] Le Witt - Masks

This example creates a geometric composition of thin vertical and horizontal stripes that cross to form a mask-like circular pattern. Two SVG masks—one revealing a filled circle and another showing a circle cut out of a full rectangle—control the visibility of the stripes, which are generated as rectangles using D3's `range` and `join`. The visualization uses `d3.select`, `.append`, and `.attr` within a React framework, rendering entirely as SVG with D3 v6.
