This line chart visualizes temperature measurements from the Data Canvas Sense Your City dataset (week_temperature_sf.csv), plotting temperature over time with a step curve. The chart uses React to render the SVG and d3’s `scaleTime`, `scaleLinear`, and `line().curve(curveStep)` to map data points, while the `AxisBottom` and `AxisLeft` components generate tick marks and labels. The visualization shows a clear stepwise temperature pattern across the week, with axis labels for "Time" and "Temperature," and the data is loaded asynchronously via d3’s `csv` function.
