This scatter plot visualizes temperature readings over time using the Data Canvas Sense Your City dataset. The visualization encodes timestamps on the x-axis and temperature values on the y-axis, with each circle representing a data point. Tooltips reveal the day of the week for each point. Built with React and D3 v5, the code uses d3.scaleTime and d3.scaleLinear for scaling, d3.extent for domain calculations, and d3.csv for data loading. SVG circles render the marks, with custom AxisBottom and AxisLeft components generating the tick marks and labels.
