This line chart visualizes one week of temperature data in San Francisco, sourced from the Data Canvas - Sense Your City project. The visualization plots timestamp on the x-axis against temperature on the y-axis, with a smooth curve connecting the data points. Built with D3 v5, the code uses functions like `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` to create the chart, rendered as SVG. The design includes labeled axes, a title, and a maroon line path with a basis curve, all styled via an external CSS file.
