This visualization shows a week of temperature readings in San Francisco, with time on the x-axis and temperature in degrees Celsius on the y-axis. A smooth, maroon line charts the hourly fluctuations, revealing daily warming and cooling cycles. The chart uses D3 v5’s `scaleTime`, `scaleLinear`, `line` with `curveBasis`, and `axisBottom`/`axisLeft` to render the SVG grid and labels. The data, from the Data Canvas - Sense Your City project, is loaded from a CSV file.
