This visualization displays temperature trends across 150 days using a red line chart, with day on the x-axis and temperature on the y-axis. The code loads climate data from a CSV file using d3.csv, then applies d3.scaleLinear for both axes and d3.line to generate the SVG path. Axes are rendered with d3.axisBottom and d3.axisLeft, while axis labels are added as SVG text elements. The chart uses a white background with a light blue page backdrop, and the line has a stroke width of 2.5 pixels.
