This line chart displays temperature variations in San Francisco over time, plotting degrees Celsius against timestamps. The visualization uses D3 v5 with SVG rendering, employing d3.scaleTime, d3.scaleLinear, d3.axisBottom, d3.axisLeft, and a d3.line generator with curveBasis. Data is loaded via d3.csv from a VizHub-hosted CSV file, with axes augmented by labels and gridlines. The chart features a teal smooth line and a monospace title, with margins positioning the plot area within a 960x500 SVG canvas.
