Temperature in San Francisco
This line plot displays one week of temperature data in San Francisco over time, with the line connecting individual observations and semi-transparent circles highlighting each data point. Rendered in SVG using D3 v5, the visualization uses `d3.scaleTime` for the time-scaled x-axis and `d3.scaleLinear` for the temperature y-axis, with grid lines from D3 axis ticks. The data is loaded from a CSV file hosted at vizhub.com, and the code constructs the chart using D3's `line` generator, `axisBottom`, and `axisLeft` APIs.
