This area chart displays a week of temperature data for San Francisco, with time on the x-axis and temperature on the y-axis, rendered as an orange filled curve with black stroke. The visualization loads CSV data from a remote URL, parses timestamps into Date objects, and uses D3 v5's `scaleTime`, `scaleLinear`, `area`, `curveBasis`, `axisLeft`, and `axisBottom` APIs to construct the SVG chart. Axis labels and a title are added as text elements, with grid lines styled via CSS classes.
