This line chart displays daily precipitation levels across Morocco in 2016, with time on the x-axis and temperature on the y-axis, rendered as a smooth curve using `d3.line` with `curveBasis`. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, `axisLeft`, and `axisBottom` to construct axes with gridlines, while SVG elements handle the rendering. Data is loaded via `d3.csv` from an external dataset, and each timestamp is parsed into a JavaScript `Date` object before scaling. The chart includes labeled axes, a title, and a maroon stroke for the line path.
