This example visualizes one week of temperature data in San Francisco, drawing on observations from the Data Canvas - Sense Your City dataset. The line chart maps timestamps to the x-axis and temperature in degrees Celsius to the y-axis, with a smooth curve applied via `curveBasis`. The visualization is built with D3 v5, using `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to render axes and grid lines. Data is loaded as CSV and parsed into date objects and numbers, then rendered as an SVG line path within a margin-framed coordinate system.
