This example demonstrates a full-screen SVG visualization of 100 vertical rectangles, each with a fixed width of 10 pixels and spacing of 20 pixels, filling the entire viewport height. It uses the Document Object Model API’s `createElementNS` method to construct SVG elements—specifically the `<svg>` and `<rect>` tags—within the `http://www.w3.org/2000/svg` namespace. The rectangles are generated in a JavaScript loop, with their `x` positions advancing by 20 pixels per iteration, creating a striped pattern across the window. The code sets the SVG’s width and height to the browser’s inner dimensions, ensuring the visualization scales responsively.

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.

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 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 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.

svg lines

This visualization displays a series of vertical rectangles across the full viewport, creating a pattern resembling spaced lines. The page generates 100 SVG rectangles, each 10 pixels wide and spaced 20 pixels apart, using raw DOM manipulation via `document.createElementNS` to construct the SVG elements. The rectangles span the full height of the window, which is dynamically set using `window.innerWidth` and `window.innerHeight`. The code relies on standard web APIs for SVG creation and attribute setting, with no external libraries or data sources involved.

Learning svg with javascript

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`.

horizontal lines

This example displays a full-screen SVG filled with 100 evenly spaced horizontal gray lines. Each line is a separate `<rect>` element, generated programmatically in a loop, with a width matching the viewport and a height of 10 pixels. The rectangles are spaced 20 pixels apart vertically, using a plain JavaScript approach with `document.createElementNS` and `setAttribute`. The visualization demonstrates a simple, static grid pattern that adapts to the browser window’s width and height. No external libraries or frameworks are used; it relies solely on native DOM and SVG APIs.

SVG Fundamentals

This example demonstrates the foundational use of SVG to generate abstract geometric patterns programmatically. It creates a series of 100 vertical rectangles that span the full height of the viewport, with each rectangle positioned sequentially along the x-axis. The rendering approach relies on the raw Document Object Model (DOM) API, using `document.createElementNS` to construct SVG elements in the `http://www.w3.org/2000/svg` namespace. The code explicitly sets attributes like `x`, `width`, and `height` on each `<rect>` element, then appends them to an `<svg>` container sized to match the window dimensions. No external libraries are used; the example illustrates how plain JavaScript and SVG can produce visual compositions inspired by minimalist art.
