This example demonstrates basic vector shapes rendered in SVG, including circles with various fill and stroke combinations, a rectangle with a yellow fill and blue outline, a diagonal line, and a curved path with a black stroke. The page uses a minimal HTML structure with inline CSS and JavaScript, with the `index.html` file defining a 960 by 800 pixel SVG canvas. The code directly specifies shape attributes such as coordinates, dimensions, and colors rather than relying on external libraries or data sources, serving as a foundational starter for building more complex visualizations with React or other frameworks.
