This area chart shows temperature variation in San Francisco over the course of a week, with time on the x-axis and temperature on the y-axis. The filled path, rendered in maroon with a smooth curve, highlights the temperature trend across the period. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, `area`, and `curveBasis` APIs to generate the SVG, with custom axes and labels. Data is loaded from a CSV file via `d3.csv`, sourced from the Data Canvas - Sense Your City project.
