This chart shows a week of temperature readings in San Francisco plotted as a line with circular markers, using a time-based x-axis and a linear y-axis. Built with React and D3 v5, it employs scaleTime, scaleLinear, extent, and line generators, with custom AxisBottom and AxisLeft components rendering SVG ticks and labels. The data, loaded via d3.csv from a weekly temperature dataset, is styled with teal marks, rounded line joins, and the Poppins font.
