This example shows a line chart rendered in SVG within a React framework, drawing a single red trend line across a 900x700 canvas. The code uses D3 v6 to create the chart structure, with linear gradients defined in the SVG defs to color both the line and axis text in brown and red tones. The visualization pulls data from the v3-source file, though the specific dataset is not visible in the provided markup. Axis labels and the chart itself rely on D3’s standard scale and axis APIs, while the overall layout is fixed by the SVG dimensions set in index.html.
