This line chart visualizes average daily temperatures in Chicago from late March to mid-April 2024. It shows a clear upward temperature trend over time, with values fluctuating between approximately 58°F and 86°F. The visualization uses D3 v5 to render an SVG line chart with a smooth basis curve, time-scaled x-axis, and linear y-axis. The code imports D3 modules like `scaleTime`, `scaleLinear`, `line`, and `curveBasis` to construct the chart, while data is loaded from a CSV file containing date and temperature columns. Axis labels and a title are styled with CSS classes, with the temperature axis rotated vertically.
