D3.JS
This example showcases a minimalist SVG visualization with a solid red background created using D3.js v5. The code selects the SVG element and applies a red background color via D3’s selection style method. It demonstrates basic SVG setup, linking to the D3 library from a CDN, and using simple D3 selection and styling APIs. The complete SVG canvas is 960 by 500 pixels, with hidden body margins, and placeholder styling for stroke lines that are not yet rendered. The example emphasizes foundational D3 syntax for styling SVG elements.
