This visualization displays a temperature trend over time using a stylized line chart rendered as SVG. The graph plots temperature readings from a San Francisco dataset on the y-axis against timestamps on the x-axis, with smooth curves generated via d3’s `curveNatural` path interpolation. The React application loads geographic data from the world-atlas TopoJSON file, though the visible chart focuses on the line plot with axes created using scaleTime, scaleLinear, and custom tick components. The chart uses d3.v5, React hooks, and a light, modern style with Poppins typography.
