This area chart displays a week of temperature readings in San Francisco, with time on the x-axis and temperature on the y-axis, using a smooth curve to connect the data points. The visualization pulls data from a CSV file hosted on VizHub and renders it as an SVG using D3 v5’s `area` generator with `curveBasis` for the smooth line. It employs `scaleTime` for the temporal axis, `scaleLinear` for temperature, and includes gridlines via custom axis ticks. Axis labels and a title are added as SVG text elements.
