This visualization displays a week of temperature readings in San Francisco, plotting each data point as a red, semi-transparent circle along time and temperature axes. The chart includes labeled axes for Time and Temperature, with a title and grid lines. The code uses D3 v5 APIs including `d3.csv`, `d3.scaleTime`, `d3.scaleLinear`, `d3.axisLeft`, and `d3.axisBottom` to load data from a CSV file and render the SVG chart within a React-based framework.
