Temperature in San Francisco Line Chart
This line chart visualizes one week of temperature in degrees Celsius for San Francisco, sourced from Data Canvas’s Sense Your City dataset. It plots timestamps on the x-axis and temperature on the y-axis, with a smooth curved line connecting the daily readings. The chart uses D3 v5’s `csv`, `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` to render the SVG. Axis labels, a title, and gridlines are drawn via the margin convention, while the single maroon path emphasizes the temperature trend.
