This example renders 100 horizontal rectangles that span the full window width, each stacked at 20-pixel intervals. The rectangles are drawn as SVG elements using D3’s `select`, `join`, and attribute setters, with a `mask` attribute referencing a `circle-mask` defined elsewhere. Data is generated programmatically via `Array.from`, mapping index values to `y` positions and fixed widths and heights. The code demonstrates a minimal React-free workflow, appending an SVG to the body and sizing it to `window.innerWidth` and `window.innerHeight`.

javascript svg

This example generates a full-screen SVG visualization using the browser’s native Document Object Model (DOM) APIs. It creates 100 vertical rectangles, each 10 pixels wide and spaced 20 pixels apart, spanning the full height of the window. The rectangles are appended to an SVG element created via `document.createElementNS`, with dimensions set from `window.innerWidth` and `window.innerHeight`. The code runs directly in an HTML page with no external libraries, demonstrating a simple programmatic approach to SVG rendering in a React-hosted environment.

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.

SVG Fundamentals

This example illustrates fundamental SVG rendering by generating a grid of vertical rectangles that stretch across the full height of the browser window. The code creates 100 rectangle elements using the Document Object Model’s `createElementNS` method with the SVG namespace, setting each rectangle’s x-coordinate and width via attributes. It leverages vanilla JavaScript to dynamically append these shapes to an SVG container that is sized to match the viewport using `window.innerWidth` and `window.innerHeight`. The result is a simple, repeating pattern that demonstrates basic SVG shape creation without external libraries.

svg circle

This example renders 100 horizontal rectangles on an SVG canvas, with a circular mask applied so only the area inside a 200-pixel-radius circle centered on the screen is visible. The rectangles are spaced every 20 pixels vertically, each 10 pixels tall and spanning the full window width. The code creates the SVG elements using the native `document.createElementNS` API, building a mask containing a white circle and attaching it to each rectangle via the `mask` attribute. The visualization demonstrates basic SVG masking and procedural element creation in a browser environment.

SVG Fundamentals

This example introduces fundamental SVG rendering by generating a grid of 100 vertical rectangles, each 10 pixels wide and spaced 20 pixels apart, across the full browser window height. The code uses native DOM manipulation with `document.createElementNS` and the `http://www.w3.org/2000/svg` namespace to construct the SVG elements dynamically in a loop. It also demonstrates viewport sizing via `window.innerWidth` and `window.innerHeight`, with CSS applied globally to remove margins and hide overflow.

Learn D3

This example demonstrates how SVG masks can create a striking visual composition using only rectangles and circles. It renders 100 horizontal and 100 vertical thin rect elements across the full viewport, with each set masked by a circular aperture defined via native SVG `mask` elements. The first mask uses a white circle on a black background, while the second inverts the colors to alternate visibility between the two rectangle sets. No D3 library calls appear in the code; instead, it relies on `document.createElementNS` and `setAttribute` for all SVG construction, making it a pure vanilla JavaScript and SVG demonstration.

SVG Fundamentals

This example demonstrates the creation of a dynamic SVG visualization that adapts to the browser window’s dimensions. It generates 100 vertical rectangles, each 10 pixels wide, positioned incrementally along the x-axis using a JavaScript loop. The code uses the raw SVG DOM API via `document.createElementNS` to construct and style the rectangles with a skyblue fill, and it logs the computed viewport size to the console. The visualization showcases fundamental SVG shape rendering with programmable layout logic.

SVG Fundamentals

This example demonstrates SVG fundamentals by rendering a grid of horizontal and vertical bars across the full viewport, with circular masks that reveal or hide portions of the pattern. The visualization uses D3’s `select` and `range` functions to generate 100 rectangles in each direction, applying masks defined via SVG `<mask>` elements with white and black circles. The code constructs the SVG scene programmatically, showing how React-based projects can manipulate vector graphics through D3’s data-join syntax and attribute setters.
