This example renders a blank 960×500 SVG canvas with an empty script tag, containing no data or visual elements. The accompanying CSS defines styles for highlighted text, black stroke lines, and green path strokes with rounded joints. Since the HTML references no external JavaScript libraries and the script is empty, the visualization shows no concrete behavior. It serves as a minimal React-ready starter template using plain SVG markup, with styling hooks prepared for future line-based D3.js visualizations.
