This example demonstrates how D3.js SVG masks can combine overlapping rectangular grids with symbolic cutouts to create intricate geometric patterns. The visualization renders 100 horizontal and vertical bars whose intersection is selectively revealed through two complementary masks. The first mask shows white space around circle, triangle, and cross symbols, while the second inverts this effect. Using D3’s `select`, `range`, `symbol`, and `symbols` APIs, the code generates SVG paths and applies mask attributes dynamically. The result is a layered interplay of shapes, highlighting SVG’s masking capabilities for pattern composition.

SVG Fundamentals

An SVG-based visualization demonstrates how masking layers create intersecting geometric patterns. The code renders 100 horizontal and vertical rectangles using D3's `select` and `range`, each masked by a circular region. Two SVG masks invert their black-and-white fills, producing a visible cross-shaped overlap at the center where the circles align. The grid lines only appear within the masked circular areas, creating a dynamic interplay of light and dark stripes against a blank canvas.

SVG Fundamentals

This example demonstrates SVG fundamentals by layering horizontal and vertical striped rectangles that intersect to create a grid, with two masks applied to each set of stripes. D3’s `select`, `range`, `symbol`, and `symbols` APIs generate the stripes and position symbol paths within the masks. The `mask1` and `mask2` masks, filled with black and white respectively, reveal or hide portions of the grid based on the symbol shapes, producing a dynamic interplay of light and dark geometric patterns across the full canvas.

SVG Fundamentals

This example demonstrates SVG fundamentals by drawing two sets of perpendicular parallel lines—horizontal bars from top to bottom and vertical bars from left to right—that intersect to form a grid. Two circular masks are applied to reveal or hide overlapping regions, creating a crossfade effect between the two line groups. The visualization uses D3’s `select`, `range`, and data join methods to generate the SVG elements, and defines two `<mask>` elements with black and white rectangles and circles to control visibility. The rendering relies entirely on SVG attributes like `width`, `height`, and `mask`, with no animation or interaction.

More complex SVG + D3

This example demonstrates SVG masking with D3, where 100 horizontal and 100 vertical rectangles render as a grid and are selectively revealed through two masks. The masks contain symbol paths from `d3.symbol` and `d3.symbols`, with one mask inverted to create contrasting visibility. Using `d3.select`, `d3.range`, and `selection.join`, the code appends rectangles and paths directly to the SVG, positioning symbols at evenly spaced intervals. The `renderMask` function accepts an inverted flag to alternate fill colors between black and white, showcasing how D3 v7 enables dynamic mask construction.

Fork of SVG Fundamentals

This example demonstrates masking in SVG by creating a grid of horizontal and vertical rectangles, each with a mask applied. Two masks are rendered using D3's `symbol` API, placing geometric shapes like circles and crosses across the canvas. One mask is inverted by using black as the background and white for the shapes, while the other uses the opposite color scheme, causing the grid lines to appear only within the symbol outlines. The visualization shows how D3 selections, joins, and the `attr` method dynamically set mask references and symbol paths.

SVG fundementals

This example demonstrates two sets of overlapping horizontal and vertical stripes, each masked by a set of symbols. It uses D3.js version 6.6.1 with the `select`, `range`, `symbols`, and `symbol` APIs to construct SVG masks. The horizontal stripes use the first mask, while the vertical stripes use an inverted second mask, revealing the symbols where the stripes intersect. The rendering is entirely SVG-based, with the code appending mask elements and rectangles to the SVG canvas.

SVG Fundamentals

This example demonstrates how SVG masks can create a circular window onto layered geometric patterns. Using the native SVG DOM API, the code constructs fifty horizontal and fifty vertical rectangles, each with vibrant default colors, and applies two different masks to control their visibility. The first mask, built from a black rectangle and white circle, reveals only the horizontal bars inside the circle, while the second mask, with inverted colors, shows the vertical bars outside the circle’s edge. The result is a clean, mask-driven interplay of striped shapes across the full browser viewport.
