This example demonstrates how D3’s `scaleTime()` maps dates to x-coordinates along a linear time axis. It plots four circles at quarterly intervals between January 2016 and January 2017, positioning them at y=200 while labeling each with its full date string. The visualization uses an SVG canvas, with data bound via D3’s selection join (`selectAll().data().join()`). The scale’s domain spans one year, and its range runs from x=60 to x=900, making temporal spacing explicit. The code imports `scaleTime` from D3’s scales module.
