This example visualizes weak temperatures in San Francisco as a smooth, maroon line chart over time. The chart uses a basis curve to connect data points, with axes labeled "Time" and "Temperature" and a title. It loads CSV data from a remote dataset, parses timestamps and numeric temperatures, and renders the visualization using D3’s `select`, `csv`, `scaleLinear`, `scaleTime`, `axisLeft`, `axisBottom`, `line`, and `curveBasis` APIs within an SVG canvas.
