This visualization shows daily temperature readings in San Francisco as a scatter plot, with each circle representing a single day’s temperature plotted against its date. The x-axis displays time using a time scale, while the y-axis uses a linear scale for temperature in Celsius. The chart includes axis labels, grid lines, and a title. Using d3.csv to load data, the code employs d3.scaleTime, d3.scaleLinear, d3.extent, d3.axisBottom, and d3.axisLeft to render the SVG elements.
