This example generates a pattern of horizontal and vertical bars overlaid with two circular masks, revealing a cross-hatched grid within a circular window. The visualization uses D3 v6 to create SVG rectangles and mask elements, with `select` and `range` from the d3 library. Data is generated programmatically with a loop for horizontal bars and `range` for vertical bars, while masks combine white and black shapes to control visibility. The result demonstrates how SVG masks can create layered geometric compositions.

D3 first steps

This example generates a full-screen grid of 100 vertical and horizontal bars using D3 selections and joins, then applies two circular SVG masks to create a striking cross-hatch pattern. Built with a React-wrapped D3 v6 setup, the code uses `select`, `range`, and `join` to bind data to rectangles, while the masks—one with a white circle on black, the other inverted—reveal and hide intersecting lines around a central focal point.

d3 tutorial

This example demonstrates a simple SVG visualization where 100 horizontal rectangles are drawn across the full window width, with a circular mask revealing only the central portion of the stacked bars. The code uses d3.select, d3.range, and the .join() method to bind data to rectangle elements, then appends an SVG mask containing a black background rect and a white circle to create the viewport effect. Rendering is handled entirely through SVG attributes, with the visualization sized dynamically to the browser window.

This example shows a full-screen pattern of intersecting horizontal and vertical bars, each rendered as a set of thin SVG rectangles. The bars are generated using `d3.range` and joined to `rect` elements, but only the central circular area is visible due to two SVG masks. The first mask reveals the horizontal bars through a white circle on a black background, while the second mask hides the vertical bars in the same region using a black circle on white. The result is a cross-hatched grid with a circular cutout, built with React and D3 v7.

d3 tutorial 4

This example uses D3 to render a full-window SVG image. It draws 100 horizontal bars, each with a height of 10 pixels and stacked vertically, to create a striped pattern across the canvas. A clipping mask, defined with the `<mask>` element, applies a white star-shaped path over the stripes, so only the area inside the star remains visible against a black background. The code uses D3's `select`, `range`, `symbol`, and `symbols` APIs to generate the star path and SVG elements.

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.

Fork of d3-get-it-right-04

This example creates an abstract pattern of horizontal and vertical bars layered over each other. It uses the D3.js library’s `select`, `range`, and `join` API to generate 100 rectangles in each direction across the full canvas. Two SVG masks with circular cutouts reveal and hide portions of the bar grids, producing a dynamic interplay of light and dark stripes. The visualization is rendered in a React environment and uses an SVG viewport that fills the browser window.

d3

This example demonstrates masked striped patterns overlaid on top of each other. It creates 100 horizontal rectangles and 100 vertical rectangles, each with a height or width of 10 pixels, spaced 20 pixels apart. The rectangles are masked using SVG masks with circular cutouts, creating a crosshatch effect with a circular reveal. The visualization uses D3 v6 with `select`, `selectAll`, and `data` joins to bind the mark arrays to the SVG elements, rendering the output as SVG in a React-styled HTML page.

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.
