This area chart shows the temperature in San Francisco over the course of a day, with time on the x-axis and temperature on the y-axis. The data is loaded from a CSV file using `d3.csv`, and the chart is rendered as an SVG using D3 v5. The area path is generated with `d3.area` and a `curveBasis` interpolation, while axes are created using `axisLeft` and `axisBottom` with custom tick styling. The visualization includes labeled axes and a centered title.
