This area chart visualizes one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City. The chart uses a filled path to show temperature fluctuations over time, with axes labeled "Time" and "Temperature." The code leverages d3.csv, d3.scaleTime, d3.scaleLinear, d3.area, and d3.curveBasis to generate the smooth area shape. SVG rendering is employed, with axis ticks and gridlines styled via CSS.
