This scatter plot visualizes temperature readings over time from the Data Canvas Sense Your City dataset. The code uses d3.scaleTime and d3.scaleLinear to map timestamps and temperatures, with React rendering SVG circles for each data point. Weekly temperature trends are shown across a one-week period, with ticks formatted using d3.timeFormat. The visualization includes axis labels and tooltips via SVG title elements, loaded asynchronously with d3.csv in a custom useData hook.
