This example visualizes weekly temperature readings from San Francisco, plotting them as a time-series line chart with a natural curve fitting. The React-based application uses D3.js scales to map time and temperature data, with SVG-rendered axes and tick marks. The data is loaded externally via a CSV file and formatted through a custom hook. The line chart includes labeled axes for time and temperature, with a minimalist teal-styled design applied through the Poppins font.
