This line chart visualizes temperature readings over one week from the Sense Your City dataset, using a smooth, natural curve through the data points. The chart is built with React and D3 scales and axes, while the line path is generated using the d3.line function with curveNatural. Both the x-axis (time) and y-axis (temperature) are labeled, and the styling uses Poppins font with a teal color scheme. The visualization is rendered as an SVG, with data loaded asynchronously via d3.csv.
