This example demonstrates how basic SVG shapes—circles, rectangles, lines, and paths—can be styled and grouped using CSS. It shows a static composition where the first circle and rectangle inherit default fills, a translated group applies shared fill and blue stroke attributes, and the `.lines` class sets black stroke width for lines while paths override the stroke to red with round line joins. The code uses the SVG API directly within an HTML document, with CSS rules in a separate stylesheet controlling presentation. No external libraries are involved.
