This line graph example displays a single smooth curve that dips and rises across a blank SVG canvas, tracing a sinusoidal-like pattern from the left edge to the right. The path is drawn with a thick black stroke and rounded line caps on a 781×554 viewBox. The visualization is rendered using React with inline SVG, with the line’s coordinates hardcoded in one path element. No data source or interactivity is present; the example focuses purely on basic SVG path rendering within a minimal HTML page.
