This line chart visualizes one week of temperature readings in San Francisco, plotting time on the x-axis against temperature on the y-axis. The visualization loads CSV data from a remote dataset and renders both a connected line path and semi-transparent green circles for each data point. Built with D3 v5, the code uses scaleTime and scaleLinear for axes, axisBottom and axisLeft for ticks, and the line generator to create the path. SVG is the rendering approach, with custom axis labels and a title.
