This line chart visualization displays a week of temperature data in San Francisco, using a smooth curve to connect each timestamped measurement. The chart includes labeled axes for time and temperature, with a title and clean grid lines. The code loads the dataset via `d3.csv` from a VizHub URL and renders the chart as an SVG using D3 v5 APIs including `scaleTime`, `scaleLinear`, `line`, `curveBasis`, `axisBottom`, and `axisLeft`. Styling is applied through CSS classes, and the line is drawn with a green stroke on a neutral background.
