This clusterplot displays one week of temperature data in San Francisco, plotting time along the x-axis and temperature along the y-axis. Red semi-transparent circles mark individual readings, creating dense clusters where values repeat. The visualization uses d3.csv for data loading, d3.scaleTime and d3.scaleLinear for axes, and d3.axisBottom and d3.axisLeft with gridlines. Circles are rendered as SVG elements with opacity set in CSS.
