This line chart visualizes one week of temperature data in Bergenfield, NJ, with time on the x-axis and degrees Fahrenheit on the y-axis. The code loads data from a CSV URL using D3’s `csv` method, then renders the chart with SVG. It uses `scaleTime` and `scaleLinear` for the axes, `axisBottom` and `axisLeft` for ticks, and a `line` generator with `curveBasis` to draw a smooth maroon path for the temperature trend.
