Temperature in San Francisco Area Chart
This area chart displays one week of temperature readings in San Francisco, with time along the x-axis and degrees Celsius on the y-axis. The visualization uses d3.area with a curveBasis smoothing to create a filled path beneath the temperature line, while d3.scaleTime and d3.scaleLinear map the data domain to screen coordinates. Axes are rendered using d3.axisBottom and d3.axisLeft, with the data loaded from a CSV file via d3.csv. The SVG output is styled with CSS, featuring a maroon fill and opacity for the area path.
