This visualization plots Syria’s mean life expectancy at birth for each year from 1990 to 2021, with points positioned along the x-axis by year index and the y-axis scaled by life expectancy. Using d3.v7, the code draws circles via the `xPosition` module, while additional unused modules (`hue`, `shape`, `size`, `length`) demonstrate alternative encodings. The data array contains 32 yearly values, rendered as a simple dot plot across the full viewport.
