This visualization displays a week of temperature readings in San Francisco as a smooth line chart, with time on the horizontal axis and temperature on the vertical axis. The data is loaded from a CSV file using d3.csv, then rendered as an SVG through React components. The chart uses d3.scaleTime and d3.scaleLinear to map the timestamp and temperature values, while d3.line with curveNatural generates the curved path connecting the data points. Custom axis components and a simple tooltip via SVG title elements are included.
