This example visualizes the temperature in San Francisco over time using a smooth, orange line chart generated with D3.js v5. The SVG rendering displays time on the x-axis and temperature on the y-axis, with styled axis labels and a title. The code fetches data from a CSV file, scales the axes with `scaleTime` and `scaleLinear`, creates grid lines via `axisBottom` and `axisLeft`, and draws the curve using the `line` and `curveBasis` functions.
