This line chart displays one week of temperature data in degrees Celsius for San Francisco, sourced from Data canvas-sense your city. The visualization uses D3 v5 to render an SVG with a time-scaled x-axis and linear y-axis, featuring red circles for individual data points connected by a thick red line path. The code implements `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` APIs, with gridlines and axis labels styled via CSS.
