This line chart visualizes daily temperature readings for New York, San Francisco, and Austin from the Data Canvas Sense Your City dataset. It displays how temperatures fluctuate over time, with a single blue line representing one selected city. The visualization uses D3 v5 to parse the tab-separated data, construct time and linear scales, and render the SVG path. Axes are generated with `d3.axisBottom` and `d3.axisLeft`, while the line itself is created using the `d3.line` generator.
