This line chart visualizes one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City, with time on the x-axis and temperature in Celsius on the y-axis. The visualization uses D3 v5 to load CSV data, apply linear and time scales, render axes, and draw a smooth basis-curve line. SVG is used for rendering, and the chart includes axis labels, grid lines, and a title, with styling applied via CSS.
