This example shows a stylized line chart of weekly temperature readings in San Francisco, plotting time on the x-axis and temperature on the y-axis. The chart uses React components to render SVG elements, with d3.scaleTime and d3.scaleLinear for scales, d3.line with curveNatural for the smooth path, and d3.timeFormat for axis tick labels. Data is loaded via d3.csv from a remote dataset, and the visualization includes labeled axes and a minimalist Poppins font styling.
