This line chart shows daily average temperatures in Germany from 2020 to 2024, with dates on the x-axis and temperature in degrees Celsius on the y-axis. The code filters the CSV data for Germany, parses dates with `d3.timeParse`, and uses `d3.scaleTime` and `d3.scaleLinear` to map the data. A red path is drawn using `d3.line`, with axes and labels added via `d3.axisBottom` and `d3.axisLeft`. The chart renders as an SVG in the browser.
