This line chart visualizes hourly temperature readings in Stockport over several days in February and March 2020, showing the fluctuating warmth and cold. The chart is rendered as an SVG element using D3.js, with data loaded from a CSV file. The visualization uses `scaleLinear` and `axisBottom`/`axisLeft` for axes, and plots the temperature values as points connected by a line, with a green border styling the SVG.
