This example demonstrates interactive SVG animations triggered by CSS transitions. It plays with two circles: one changes its fill color and stroke width on hover, while the main scene in a separate SVG uses a hardcoded path and circles with a drop shadow filter to illustrate positioning. The code uses raw SVG elements with CSS styling for hover effects, relying on a `transition: all 500ms` property. It also includes a broken radial gradient definition, alongside basic text rendering, and is built with React and rendered as SVG.
