This line chart displays temperature readings over the course of a week, with time on the x-axis and temperature on the y-axis. The React-based visualization renders as an SVG, using d3.scaleTime and d3.scaleLinear to map data from the Data Canvas Sense Your City dataset. A path generated with d3.line and curveNatural connects the points, while circle elements provide tooltips via the title tag. Axes are built programmatically using d3.timeFormat and custom React components for bottom and left ticks.
