This line chart visualizes temperature changes over time for a week in San Francisco, using data from the Data Canvas Sense Your City Dataset. The React-based application employs D3 v5 scales and the `d3.line` function with a natural curve to draw the smooth temperature path across a time-based x-axis. Both axes are rendered as SVG elements with tick marks, while CSS styling applies a consistent teal color scheme. The visualization loads CSV data asynchronously via `d3.csv` and updates the chart once the data arrives.
