This area chart visualizes temperature fluctuations in Dallas over a one-week period, with time on the x-axis and degrees Celsius on the y-axis. The chart uses a filled, smooth curve (via `d3.area()` with `curveBasis`) to highlight the temperature wave. Data is loaded from a CSV file using `d3.csv()`, and scales are created with `d3.scaleTime()` and `d3.scaleLinear()`. Axis labels and tick marks are rendered through `d3.axisBottom()` and `d3.axisLeft()`, with the title displayed above the plot.
