This example visualizes weekly temperature data from San Francisco using a stylized line chart. The SVG rendering leverages React components for axes and marks, with D3 v5 scales (scaleTime, scaleLinear) and the curveNatural interpolation to create smooth lines. Data loads via d3.csv from a remote GitHub gist. The minimal design uses Poppins typography and muted colors, with axes rendered using custom d3 tick generation and grid lines.
