A line chart displays daily temperature readings from two weather stations in Buenos Aires (CABA) throughout 2011, using data from a CSV file. The visualization uses D3 v5 with an SVG renderer, mapping timestamps to a time scale and temperature to a linear scale. A smooth curve via `d3.curveBasis` connects the points, while axes are generated with `axisBottom` and `axisLeft`, including grid lines and rotated axis labels. Data parsing relies on `timeParse` and `csv` from D3.
