Hello world
A minimal React-driven SVG scene displays a single gray circle centered on a blank canvas. The example demonstrates the foundational structure of a web-based visualization, using hardcoded coordinates for the circle’s position and radius. It renders via SVG elements defined directly in the HTML, with CSS resetting margins and hiding overflow. The code illustrates the simplest possible data-binding setup, where no external libraries or data sources are employed beyond the basic React starter template referenced in the documentation.
