This area plot visualizes daily temperature changes over time, with the x-axis representing dates and the y-axis showing temperatures in degrees Celsius. The chart uses a single steelblue filled area to emphasize the temperature curve against a white background. Built with D3 v7, the visualization employs `d3.csv` to load weather data from a remote CSV file, `d3.scaleTime` and `d3.scaleLinear` for axes, and `d3.area()` to generate the filled path. SVG rendering includes labeled axes and five evenly spaced ticks on the time axis, while the data processing parses dates and converts temperature values to numbers.
