This line chart visualizes one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City. The chart displays temperature values over time, with a maroon curved line and interactive tooltips that reveal the exact temperature and date on hover. Built with D3 v5, it uses `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` to generate the SVG rendering. The visualization includes a titled axis, styled tick labels, and custom tooltip shapes, all implemented with SVG elements and CSS filters.
