This example shows nightly low temperatures in San Antonio over a week in April 2020. A smooth maroon line connects time-stamped data points, with gray gridlines and labeled axes for time and temperature. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and a `line` generator with `curveBasis`. Data is loaded from a CSV file and rendered as an SVG, with axes and labels styled via CSS.
