This visualization displays temperature readings over time in San Francisco, with time on the x-axis and temperature on the y-axis. The line chart uses a smooth curve to show trends across the dataset. The code imports specific D3 v5 modules through ES6 imports, including `scaleTime`, `scaleLinear`, `line`, and `curveBasis` for the path smoothing. It loads CSV data from a remote URL, parses the temperature as numbers and timestamps as dates, then renders SVG axes with grid lines and a styled title.
