Shapes with SVG and CSS
This example demonstrates fundamental SVG shape rendering within a React-based visualization gallery. It shows circles, rectangles, lines, and paths positioned on a 960×500 canvas, with styling controlled through both inline attributes and CSS. The code uses raw SVG elements and CSS for presentation, including a group (`<g>`) that applies shared fill and stroke properties, and another group with stroke attributes for the line and path. No data is loaded; the shapes are statically defined in the HTML markup.
