This stylized line chart displays temperature readings over the course of a week, using a smooth, natural curve to connect data points. It renders as an SVG within a React application, leveraging D3 v5 functions like `scaleTime`, `scaleLinear`, `line`, and `curveNatural`. A scatter of circles marks each individual observation, with tooltips showing the day for each point. The chart draws its data from a CSV file containing San Francisco weekly temperature data, sourced from the United Nations World Population Prospects.
