This line chart visualizes one week of temperature data in San Francisco, with time on the x-axis and temperature in degrees Celsius on the y-axis. The chart is rendered as an SVG using D3 v5, employing `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` for a smooth curve. The data is loaded from a CSV file hosted on VizHub, which originates from the Data Canvas - Sense Your City initiative. Custom styles define the title, axis labels, and maroon line with a steelblue hover state.
