This example visualizes a week of temperature readings in San Francisco as a smooth line chart, with time on the x-axis and temperature on the y-axis. The chart includes labeled axes, gridlines, and a title. The visualization is rendered as SVG using D3 v5, employing `scaleTime`, `scaleLinear`, `line` with `curveBasis`, and `axisLeft` and `axisBottom` for the axes. Data is loaded from a CSV file hosted on VizHub.
