This line chart displays one week of temperature in San Francisco, measured in degrees Celsius, with the title “A Week in San Francisco.” The data is sourced from Data Canvas - Sense Your City. The chart uses d3.scaleTime and d3.scaleLinear for the axes, d3.axisBottom and d3.axisLeft for ticks, and d3.line with curveBasis to render the smooth temperature path. It is drawn as an SVG with a maroon stroke, and the code imports d3.v5 modules via ES6 syntax.
