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.

This example demonstrates a geometric masking effect by layering vertical and horizontal rectangles on an SVG canvas. Using D3 v7, it creates 100 vertical bars and 100 horizontal bars across the viewport, applying two SVG masks to reveal intersecting shapes. The first mask uses a white background with a black circle, while the second inverts the pattern, producing a cross-shaped visual interaction. The code relies on D3 selections, the `range()` generator, and SVG `mask` elements to achieve the composition.

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 builds a full-screen SVG visualization of 50 horizontal rectangles arranged in a vertical sequence, with their heights and spacing varying incrementally by index. A circular mask reveals only the central portion of the layered bars, creating a lens-like effect against a white background. The code uses D3 v7 selections and the `range()` generator to bind data, then appends rectangles via `join()`. A dedicated `<mask>` element contains a single white circle positioned at the center, demonstrating basic D3 masking and data-binding techniques.

A grid of thin horizontal and vertical rectangles covers the screen, but two circular masks reveal only the central region: one mask shows the horizontal lines, the other shows the vertical lines, creating a crosshatch pattern inside an overlapping circle. The example uses D3 v7’s `select`, `range`, and `join` to generate 100 SVG `<rect>` elements per direction, with `mask` elements and black/white filled circles controlling visibility. The full-screen SVG renders in the browser with no external data.

This example shows how D3 version 7 can create layered geometric patterns by combining SVG masks with repeated rectangles. The visualization produces four distinct regions: a striped horizontal pattern with a cut-out square, a vertical stripe pattern, and two sections where horizontal or vertical bars are masked by a circle and square. The code constructs SVG elements directly using the DOM API, building masks (mask1 through mask4) that define which parts of the rectangles are visible. The approach relies on creating rectangles of varying widths and heights, applying masks that contain contrasting black and white shapes, and iterating 30 or 60 times to generate the repeating bar patterns across the screen.

This example demonstrates a generative grid of horizontal and vertical striped bars rendered as an SVG, overlaid with circular mask effects that reveal or conceal portions of the pattern. The code uses D3 v3’s selection, selection, range, symbols, and symbol APIs, appending rectangles to an SVG canvas sized to the window. Two masks are created via the renderMask function, each with a path drawn from the symbol API’s circle shape, applying inverted fill logic to produce contrasting visibility. The visualization is purely procedural, with no external data source.

This example generates a grid of horizontal and vertical stripes that intersect to create a geometric pattern. It uses SVG masks with circles to reveal or hide different sections of the stripes, producing a composition reminiscent of Sol LeWitt’s wall drawings. The code leverages D3 v7 selection methods, including `select`, `append`, and `join`, along with `range` to create 100 rectangles for each direction. The visualization is fully responsive, sized to the browser window, and includes hover effects that change the fill color to magenta.
