This example re-implements a reusable scatterplot using D3’s `scaleLinear` and `scaleTime` for axes, with data points rendered as SVG circles via `select` and `join`. It plots hard-coded yearly percentages against dates, showing a decreasing trend from 1986 to 2021. The visualization uses a simple layout with left and bottom axes, generated through `axisLeft` and `axisBottom`, within a full-window SVG. The data is local, not from the referenced Iris CSV.
