This interactive line chart displays temperature readings over the course of a week, using a smooth natural curve to connect data points. The visualization uses React with D3.js version 5, specifically leveraging the d3 scaleTime and scaleLinear APIs for axis scaling, and the line and curveNatural functions from D3 to render the path. The SVG-based chart includes formatted time labels on the x-axis and temperature values on the y-axis, with data loaded from an external CSV file.
