This line chart displays one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City. The visualization uses a smooth curved line to connect data points, with the x-axis representing time and the y-axis showing temperature in degrees Celsius. The chart is rendered as an SVG using D3 v5, employing d3.scaleLinear, d3.scaleTime, d3.axisBottom, d3.axisLeft, and d3.line with curveBasis for the path. The data is loaded from a JSON file using d3.json, and the chart includes labeled axes and a title.
