This chart displays temperature readings in San Francisco across a week, plotting each temperature value as a circle along time-based and temperature-based axes. The visualization uses D3 v6 to load CSV data, scale time and linear axes with `scaleTime` and `scaleLinear`, and render the SVG with `axisBottom` and `axisLeft` gridlines. Axes labels and a title are added, with circles styled in steelblue via CSS. The data comes from an external CSV URL, and the chart includes a time axis labeled “Time” and a temperature axis labeled “Temperature”.
