This example creates a hundred horizontal and vertical striped rectangles overlaid to form a grid, with a symbol-shaped hole cut through the pattern. The code uses d3.select, d3.range, and d3.join to bind data to SVG rect elements. Two SVG masks, one inverted and one normal, are built with d3.symbol and a d3.symbols[0] path (a circle) to punch a central circular reveal. The result shows layered d3.mask and d3.symbol APIs combined on a full-window SVG canvas.

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.

Fork of Fork of Fork of Fork of SVG Fundamentals - D3 (group)

This example demonstrates a grid-based pattern created by overlaying horizontal and vertical rectangles, each clipped by a circular mask to reveal a central window. The visualization uses D3’s `select`, `range`, `append`, and `join` APIs to generate 100 vertical and 100 horizontal bars, which are grouped in separate `<g>` elements. Two SVG masks (`circle-mask` and `circle-mask-2`) apply inverse coloring to the bars, producing a crosshatched effect that is visible only within the circular region. The code runs in React and renders fully with SVG, drawing on D3 version 7.6.1.

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.

d3-get-it-right-04

This example uses React with D3 v6 to generate an SVG visualization of intersecting horizontal and vertical stripes. The code creates 100 rectangular bands in each direction, then applies two SVG masks: a diamond-shaped mask formed with a `d3.symbol` path, and a circular mask created with a basic SVG circle. The masks reveal the underlying stripes in geometric patterns, demonstrating how D3's `select`, `range`, and `join` methods can construct layered SVG elements with custom clipping. The visualization dynamically fills the browser window using `window.innerWidth` and `window.innerHeight`.

Full Fork of D3 Starter

This example demonstrates how D3 SVG masks can create overlapping geometric patterns. It generates 100 horizontal and 100 vertical rectangles, then applies two distinct masks with inverted fill rules to reveal or hide different regions. The code uses D3’s `select`, `range`, `symbols`, and `symbol` APIs to draw predefined symbol shapes within each mask. The visualization fills the browser window, with symbol paths placed at regular intervals across the width, producing a dynamic interplay between the grid lines and masked shapes.

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 Fork of Fork of SVG Fundamentals - D3

This example demonstrates a full-screen grid of horizontal and vertical bars revealed through two circular masks. The visualization uses D3’s `select`, `range`, and data joins to generate 100 rectangles in each orientation, with CSS masks defining a central circular viewport. Two SVG masks—one with a black background and white circle, another inverted—control which bar segments remain visible, creating a crosshatch pattern that fades at the edges. The rendering relies on the SVG `<mask>` element and D3’s `join` API.

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.
