This example demonstrates the fundamental use of SVG for data visualization, displaying a single brown circle positioned at coordinates (50, 50) with a radius of 50. The visualization is rendered through an inline SVG element within an HTML page, using only native SVG markup without any JavaScript or external libraries. The circle’s placement and styling are defined directly through SVG attributes (cx, cy, r, fill), showing the basic building blocks for creating geometric shapes in a browser. The example serves as a minimal starting point for understanding how SVG primitives form the foundation for more complex visualizations.
