This example demonstrates the foundational use of SVG by creating an empty drawing surface and placing a single small rectangle on it. The code creates SVG elements programmatically using the `document.createElementNS` API with the SVG namespace, setting the canvas dimensions to 960 by 500 pixels. A rectangle is then added at coordinates (100, 100) with a width and height of 10 pixels each. This bare-minimum approach, using plain JavaScript without any libraries, illustrates how to construct vector graphics from scratch for later data visualization.

SVG fundamentals

This example demonstrates the fundamental building blocks of SVG by constructing a single rectangle using raw DOM manipulation. The code programmatically creates an SVG element and a rect child node via the `document.createElementNS` API, setting explicit width and height attributes of 960 by 500 pixels for the canvas and 100 by 100 for the shape. It shows how to manually build SVG graphics without any visualization library, relying solely on native browser methods and CSS styling for the page layout. The rectangle is appended directly to the body, illustrating the basic SVG creation workflow.

SVG fundamentals

This example demonstrates the foundational structure of an SVG-based visualization, presenting an empty `<svg>` element within a minimal HTML document. The code establishes the essential setup for creating vector graphics on the web, with the SVG canvas ready to receive drawing instructions. The example uses plain HTML and CSS to define the page structure, while JavaScript is noted as the scripting language for future dynamic behavior. It serves as a bare-bones template, illustrating the core components needed to begin building interactive data visualizations with SVG, a powerful and scalable format for rendering shapes, paths, and text.

SVG fundamentals, baby

This example demonstrates the foundational steps of creating and styling SVG elements using plain JavaScript. It creates an SVG container that fills the entire browser window using the `document.createElementNS` API with the SVG namespace. The code then appends a rectangle with a fixed width of 100 pixels and height of 50 pixels, filling it with black via the `setAttribute` method. The example relies entirely on native browser APIs—no external libraries such as D3 or React—though the metadata notes the framework as React, which is not used in the visible code.

SVG Fundamentals

This example demonstrates the absolute essentials of SVG rendering, starting with a minimal HTML page that provides a blank canvas for drawing. The code establishes the foundational structure for creating vector graphics, using no external libraries to show the raw capabilities of SVG and the DOM. It emphasizes the simplicity of defining shapes directly in markup, with the index.html file containing only the document skeleton and title. The example serves as a starting point for understanding how CSS and JavaScript can be layered onto SVG elements, preparing users for more complex visualization frameworks.

SVG fundamentals

This example demonstrates the fundamental building blocks of SVG graphics within a minimal HTML page. It presents a blank canvas with no explicit visualization, serving as a template for creating vector-based content. The code uses standard HTML elements and connects to external CSS and JavaScript files, as noted in the README, though the provided `index.html` contains no inline styling or scripting. It is a direct, bare-bones starting point for future SVG work.

This example displays a single empty SVG canvas with a small black square in the upper-left corner, created entirely through JavaScript. The code uses the Document API’s `createElementNS` method to construct the SVG namespace elements and `setAttribute` to set the canvas dimensions (960 by 500) and the rectangle’s size (100 by 100). The SVG is appended directly to the page body, with no external data source or interaction, demonstrating the lowest-level programmatic approach to SVG generation without any helper libraries.

SVG Fundamentals

This example demonstrates fundamental SVG rendering concepts using a minimal HTML page with embedded JavaScript and CSS. It shows how to create and manipulate basic SVG elements directly in the browser, with no external libraries beyond the native DOM API. The page initializes a blank SVG canvas and illustrates the core building blocks of vector graphics, such as coordinate systems and element structure. The code relies on standard JavaScript methods like `document.createElementNS` and `setAttribute` to construct SVG shapes programmatically, providing a foundation for more advanced visualization frameworks like React.

SVG Fundamentals

This example demonstrates the foundational shapes used in SVG graphics, including a circle, a rectangle, and a line rendered within a 900 by 500 canvas. It showcases how CSS styling controls the presentation of a message, while inline SVG attributes define the geometry and appearance of each shape, such as the rectangle’s red fill and black stroke. The code uses raw SVG elements in an HTML page with embedded JavaScript and CSS, serving as a minimal starter for understanding vector graphics without external libraries.
