This example shows a scatter plot of temperature readings over time from the Data Canvas Sense Your City dataset. Each circle represents a temperature measurement, with the x-axis displaying days and the y-axis showing temperature values, using tooltips for precise day information. The visualization is built with React components that render SVG elements, using D3’s `scaleTime`, `scaleLinear`, `extent`, and `csv` for data loading and scaling. The code defines reusable axis and mark components, with axis labels and tick formatting applied via React props.
