This scatter plot visualizes temperature readings over time from the Data Canvas Sense Your City dataset, displaying each observation as a circular mark positioned by a time-based x-scale and a linear y-scale. The React components render SVG axes with tick marks, while the Marks component generates circles with native tooltips showing the formatted date. Using d3.csv for data loading, d3.scaleTime and d3.scaleLinear for scales, and d3.timeFormat for tick labels, the chart emphasizes temporal patterns in temperature data with clear axis labels and a minimalist design.
