This visualization shows a week of temperature readings in San Francisco as a smooth line chart, with points marking each hourly measurement. The time axis uses a time scale and formats tick labels as abbreviated weekday names. Built with React and D3 v7, the chart uses `scaleTime`, `scaleLinear`, `line` with `curveNatural`, and custom `AxisBottom` and `AxisLeft` components to render the SVG. Data comes from the Data Canvas Sense Your City API, loaded via `csv`, with tooltips on points displaying the formatted timestamp.
