This line chart displays one week of temperature in degrees Celsius for San Francisco, with data sourced from Data Canvas - Sense Your City. The visualization plots monthly time points against temperature values on a smooth maroon curve, using an SVG rendering approach within a 960 by 500 viewport. The implementation relies on D3 v5 utilities including `scaleTime`, `scaleLinear`, `line`, `curveBasis`, and `axisLeft`/`axisBottom` for axes, while parsing date strings via `timeParse`. The chart includes styled axis ticks and a filled circle layer commented out in the code.
