This line chart visualizes one week of temperature data in San Francisco, sourced from Data Canvas - Sense your City. The chart plots temperature in degrees Celsius along the y-axis against time on the x-axis, with a smooth maroon curve drawn using a basis interpolation. The visualization is rendered as an SVG using D3 v5, employing `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and the `line` generator with `curveBasis` to create the path. Grid lines and labeled axes provide context, while the title “A week in San Francisco” appears above the plot.
