This visualization shows daily temperature readings in San Francisco over time, with each data point rendered as a circle positioned by date on the x-axis and temperature on the y-axis. The chart includes labeled axes, gridlines, and a title. The code uses d3.csv to load the data, d3.scaleTime and d3.scaleLinear for scaling, and d3.axisBottom and d3.axisLeft to generate the axes, all rendered as SVG within a 960×500 viewport.
