This example shows a grid of horizontal and vertical stripes overlaid on a full-screen SVG, with two complementary star-shaped masks cutting through the pattern. The first mask reveals the horizontal stripes through a white star on black, while the second mask applies the inverse effect to the vertical stripes. The visualization uses D3 v7’s `range`, `selectAll`, and `symbol` API to generate 100 rect elements per orientation and construct the star paths via `symbol(symbols[4], 100000)`. Masks are defined with custom `mask` elements and applied via the `mask` attribute, producing a layered, intersecting star composition.

d3 simbols

A grid of horizontal and vertical stripes alternates through two SVG masks to reveal a large star-shaped symbol at the center. The example demonstrates D3’s `symbol` and `symbols` API to generate the star path, combined with `mask` elements to create intersecting stripe patterns. Fifty rectangles are drawn in each direction using `d3.range` and `join`, with the horizontal set masked by an inverted white-on-black layer and the vertical set by its opposite. The result shows how layered masks can produce dynamic visual interferences.

D3 Shapes SVG Fundamentals

This example demonstrates how D3 SVG masks can create geometric patterns from overlapping rectangular bands. Two sets of perpendicular stripes, each consisting of 100 horizontal and vertical rects, are filtered through circular mask shapes generated with the `symbol` API. The first mask uses a filled star symbol to hide the horizontal lines, while the second, inverted mask reveals the vertical lines through the same symbol shape. The code uses `d3.select`, `d3.range`, and `d3.symbols` with the `join` pattern to render the full-screen SVG grid.

D3_Sol

This example overlays two sets of alternating horizontal and vertical stripes, each masked by a pattern of D3 symbols (such as circles, crosses, and diamonds) centered on the canvas. The first mask uses solid shapes on a white background, while the second inverts the fill, creating a contrasting lattice. Built with React and D3 v7, it uses `select`, `range`, `symbols`, and `symbol` to generate SVG elements, with `mask` applied to each stripe group to reveal the symbol shapes through the grid.

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.

d3d3d3 3

This example generates a grid of 100 horizontal and vertical stripes, each using a mask to reveal differently-shaped symbol outlines at the center of the screen. The horizontal bars are masked by shapes like circles and crosses, while the vertical bars are masked by their inverses, creating a striking geometric interplay between foreground and background. Built with React and D3, the code uses `d3.range`, `d3.symbol`, and `d3.symbols` to construct paths, with masks defined via SVG and applied using the `mask` attribute. The visualization renders entirely through SVG, with a flickering effect caused by the contrasting masked regions.

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 start

This example creates a striped grid of horizontal and vertical rectangles, each masked so that the overlap reveals alternating symbol shapes. The visualization uses D3 v6’s `symbol` API to draw seven distinct shapes—circle, cross, diamond, square, star, triangle, and wye—as SVG paths inside two mask definitions. The masks are applied via the `mask` attribute to the rects, which are generated with `d3.range` and `join`. The page captures the full window dimensions, scaling the SVG and grid accordingly, and demonstrates a minimal React-free setup with D3 selections.

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.
